How Many Samples Should a Clothing Brand Make Before Bulk Production?

Learn how many clothing samples to make before bulk production, including fit samples, size sets and pre-production samples, plus approval tips for fashion brands.

Quick Answer: How Many Clothing Samples Do You Need Before Bulk Production?

Most clothing brands should plan for 2–4 sample rounds per style before bulk production, although the exact number depends on design complexity, fit requirements, fabric availability, and how complete the original specifications are. A simple garment developed from an established pattern may need fewer rounds, while a new technical jacket, complicated outerwear design, or garment with extensive custom details may need more.

A practical sampling plan often includes:

First prototype sample: Checks the overall design, silhouette, and construction feasibility.
Fit sample or revised sample: Checks measurements, proportions, comfort, and fit corrections.
Pre-production (PP) sample: Confirms the final materials, colors, trims, branding, construction, and finishing before bulk production.
Size set sample, when necessary: Checks whether the garment fits correctly across the intended size range.

These stages do not always require four separate physical samples. One sample may serve more than one purpose when the design is straightforward and the materials and specifications are sufficiently developed. However, a prototype made with substitute fabric should not automatically be treated as final production approval.

The most important rule is to approve the correct final sample before authorizing bulk production. Do not approve a large order simply because the first sample looks acceptable.

For fashion brands working with a custom jacket manufacturer, the goal is not to make as many samples as possible. It is to make enough samples to resolve important uncertainties before those uncertainties become expensive production problems.

Why the Number of Clothing Samples Matters Before Bulk Production

A Clothing Sample Is More Than a Preview of the Final Product

A garment sample is a physical development tool. It helps a clothing brand and its manufacturer evaluate whether the proposed design can be produced according to the intended specifications.

A sample can reveal issues that are difficult to identify from a sketch, digital mockup, or technical drawing alone.

For example, a jacket may look correct in a design illustration but have sleeves that are too long, pockets that sit too low, a collar that does not hold its shape, or a zipper that does not work smoothly with the selected fabric.

Sampling helps identify these issues while changes are still manageable.

Depending on the product, a clothing sample review may cover:

Overall garment shape and silhouette
Measurements and fit
Fabric composition, weight, and hand feel
Lining and interlining
Stitching and seam construction
Zipper, buttons, snaps, and other hardware
Pocket size and placement
Print, embroidery, patches, and logos
Labels, hangtags, and packaging
Washing, shrinkage, or other relevant performance characteristics

Not every item requires a separate sample. The objective is to confirm the relevant requirements at the appropriate stage.

What Happens If a Brand Makes Too Few Samples?

Insufficient sampling can allow unresolved issues to enter bulk production.

A small fit problem in a single sample may become a major problem when hundreds of garments are produced. Incorrect measurements, an unsuitable fabric, inconsistent logo placement, or an unapproved trim substitution can affect the entire order.

Possible consequences include:

Costly alterations or rework
Delayed production and shipment
Higher inspection and replacement costs
Unsold inventory due to poor fit
Customer complaints and returns
Disputes between the buyer and manufacturer

The risk is especially important when a brand is developing a new pattern or using unfamiliar materials.

Can Making Too Many Samples Also Be a Problem?

Yes. Repeated sampling without a clear approval process can increase development costs and delay a product launch.

Common reasons include changing design details after each round, providing incomplete feedback, selecting fabrics too late, and introducing new branding requirements after the previous sample has already been approved.

A more efficient approach is to assign a specific purpose to each sample round and consolidate feedback before requesting the next version.

For a broader explanation of the development stages, see JIMJACKETS' Jacket Sampling Process guide.

How Many Sample Rounds Should a Clothing Brand Plan For?

One Sample Round: When Is It Enough?

One sample round may be sufficient for a relatively simple garment when the brand already has a proven pattern, the fabric and trims are established, the measurements are clear, and the manufacturer understands the construction requirements.

For example, a brand repeating an existing basic jacket design with a previously approved fabric may need fewer development changes than a brand launching a completely new silhouette.

However, making one sample and approving it immediately is not always the same as completing a reliable sampling process.

Before bulk production, the brand must still confirm that the sample represents the intended production materials and construction. If the initial sample uses substitute materials, has unresolved fit issues, or lacks final branding, additional approval work may be necessary.

Use one sample round only when the product is sufficiently established and all critical production requirements can be verified.

Two Sample Rounds: A Practical Option for Straightforward Designs

Two rounds can work well for relatively simple garments with clear specifications.

A typical process may look like this:

Round 1 — Initial sample: Review the design, fit, measurements, construction, and material suitability.

Round 2 — Revised or final sample: Confirm the agreed corrections and verify the details required for production approval.

This approach may suit established T-shirt styles, simple overshirts, basic casual jackets, or repeat products when the fabric and pattern are already familiar.

If the second sample still has unresolved issues, the brand should not force approval simply to maintain the planned number of rounds.

Three Sample Rounds: A Useful Planning Baseline for Custom Clothing

Three rounds are a practical planning baseline for many new custom apparel styles, especially when the brand needs to validate design, fit, and final production details.

A possible sequence is:

First prototype to check the design and construction.
Fit or revised sample to correct measurements and proportions.
Final approval sample using the appropriate production materials and details.

The actual sample types depend on the project. A fit sample and a pre-production sample are not interchangeable if the fit has been approved but the final fabric, trims, or branding have not.

Four or More Sample Rounds: When Should You Expect Them?

More than three rounds may be justified when a garment has complex construction, substantial pattern changes, specialized materials, technical performance requirements, or extensive customization.

Examples include:

Technical outdoor jackets
Insulated puffer jackets
Waterproof garments with specified performance requirements
Leather jackets with complex panel construction
Denim jackets requiring wash development
Varsity jackets with custom patches and multiple materials
Products requiring extensive grading across sizes
Garments with several rounds of print or embroidery approval

Four or more rounds may also occur when the initial brief is incomplete or the buyer changes key requirements during development.

The best way to control additional rounds is to identify the unresolved issue, define the required correction, and agree on what must be approved next.

Which Types of Clothing Samples Are Needed Before Bulk Production?

1. Prototype Sample: Confirm the Initial Design

The prototype, often called a proto sample, is the first physical version of a proposed garment.

Its purpose is to determine whether the design concept can be translated into a workable product.

A prototype review may focus on:

Overall silhouette
Garment proportions
Basic construction
Collar, hood, sleeve, and pocket design
General material suitability
Initial pattern feasibility

The prototype may use substitute materials if the intended bulk fabric is not yet available. Any substitutions should be documented so the brand does not mistake an early development sample for a finished production reference.

A prototype is especially useful for new clothing brands that have a sketch, reference image, or early technical pack but have not yet validated the physical garment.

2. Fit Sample: Check Measurements and Wearability

A fit sample helps the brand evaluate the garment's dimensions, balance, proportions, and comfort.

This stage is important because a garment can match the general design while still fitting incorrectly.

For jackets, review:

Chest and body width
Shoulder width
Body length
Sleeve length
Armhole shape and mobility
Collar height and shape
Hem and cuff proportions
Ease over the intended layers of clothing

Evaluate the sample on an appropriate fit model or dress form, and measure it against the agreed measurement chart.

Record the exact measurement points and acceptable tolerances. Comments such as "make it slightly bigger" are less useful than specifying which measurement needs to change and by how much.

If the brand changes the fabric after fitting, the fit may need to be checked again because different materials can affect garment drape, bulk, and construction.

3. Revised Sample: Confirm That Corrections Have Worked

A revised sample incorporates the changes requested after the previous review.

This round should not simply repeat the same inspection. It should verify whether the specific issues identified earlier have been corrected.

For example, if the first jacket sample has sleeves that are 2 cm too long, the revised sample should be checked against the updated sleeve measurement.

If the collar shape, pocket placement, or zipper length has changed, those details should be checked as well.

Maintain a version history so the brand and manufacturer can distinguish between the original sample, revised sample, and approved production reference.

4. Pre-Production Sample: Confirm Bulk Production Readiness

A pre-production sample, commonly called a PP sample or PPS, is used to verify the agreed production version before bulk manufacturing proceeds.

Where practical, it should use the intended bulk fabric, color, trims, branding, construction, and finishing.

The review may cover:

Final measurements and fit
Approved fabric and lining
Color and material consistency
Zippers, buttons, snaps, and other hardware
Stitching and workmanship
Logo size and placement
Labels and care information
Washing or finishing requirements
Packaging and folding instructions

The pre-production sample should be assessed against the documented requirements, not merely against a general visual impression.

For a complex product, a separate PP sample may be important even if the brand has already approved a fit sample.

5. Size Set Sample: Check the Full Size Range

A size set sample is used to evaluate how a garment fits across multiple sizes.

A correctly fitting medium does not automatically mean that the small, large, and extended sizes will fit correctly.

Size grading can affect proportions, sleeve dimensions, armhole shape, and other fit characteristics.

A size set is particularly useful when:

Launching a new pattern
Introducing a broad size range
Developing fitted or tailored garments
Selling products where size-related returns are a major concern
Changing the base pattern or grading rules

A brand may review selected sizes or a complete size range depending on the product, budget, and risk. Agree on the size-set scope with the manufacturer before development.

6. Top-of-Production Sample: Verify the Start of Bulk Manufacturing

A top-of-production sample, or TOP sample, is taken from the early bulk production run rather than being treated as another ordinary development sample.

It can help verify that the approved product has been reproduced under actual production conditions.

Review whether the garment matches the approved reference in terms of materials, construction, measurements, branding, and workmanship.

A TOP sample does not replace the need for appropriate in-line and final inspection. It is an additional verification point, especially useful for complex or higher-risk orders.

Pre-Production Sample vs Fit Sample: What Is the Difference?

The fit sample and pre-production sample serve different purposes, even when they look similar.

Comparison Fit sample Pre-production sample

Primary purpose Validate fit and proportions Confirm the production-ready version

Measurements Major focus Confirm against approved specifications

Fabric May be provisional Should reflect intended bulk materials where practical

Trims and hardware May be provisional Final approved components

Branding May be incomplete Final approved artwork and placement

Construction Evaluated and revised Confirmed against production requirements

Approval outcome Fit corrections accepted or requested Production readiness approved or rejected

A brand should not assume that approving the fit sample automatically authorizes bulk production.

If the final fabric, color, trims, or branding differ from the fit sample, those differences need to be verified and documented.

How Many Samples Should a Brand Make for Different Types of Clothing?

T-Shirts and Basic Knitwear

A straightforward T-shirt using an established pattern may require a relatively simple process.

The brand should still verify fabric weight, hand feel, shrinkage where relevant, neckline construction, body measurements, sleeve proportions, print placement, and label details.

A second round may be necessary if the first sample reveals fit or material problems. A PP sample or equivalent final approval check is important when the production fabric, print, or branding differs from the initial sample.

Hoodies and Sweatshirts

Hoodies and sweatshirts may require extra attention to fabric weight, rib recovery, hood shape, drawcords, pocket construction, and print or embroidery.

A sample that looks correct on a hanger may behave differently when worn, particularly if the garment is oversized or made from heavyweight fleece.

Brands should evaluate the intended fit, fabric behavior, stitching, and decoration before production.

Denim Jackets

Denim jacket development can require additional work when the product includes custom washes, distressing, contrasting stitching, metal hardware, or complex panel construction.

The appearance of a washed denim sample may not be reproduced consistently unless the wash process and acceptance criteria are clearly defined.

For custom denim projects, review the fabric, fit, wash appearance, hardware, seams, and branding together. If wash development is still changing, do not assume that an earlier sample represents the final production result.

See JIMJACKETS' custom denim jacket manufacturing page.

Leather Jackets

Leather jackets can require more careful sample development because leather characteristics, panel selection, thickness, lining, hardware, and construction all affect the final garment.

Natural material variation may also need to be considered when defining acceptable differences between the approved sample and bulk production.

For a custom leather jacket, confirm the material specification, panel layout, fit, zipper and hardware details, lining, stitching, and finishing before approval.

Explore JIMJACKETS' custom leather jacket service.

Puffer Jackets and Technical Outerwear

Puffer jackets and technical outerwear can require additional development because insulation, lining, shell fabric, quilting, seam construction, and hardware interact with one another.

Depending on the product claims, the brand may also need relevant performance tests or documentation.

A visual sample alone cannot prove waterproofness, thermal performance, or other technical properties. Those requirements should be defined and tested using suitable methods.

For these products, plan sample rounds around the actual technical risks rather than relying on a fixed number.

How Much Should a Clothing Brand Budget for Sample Development?

What Determines Clothing Sample Cost?

There is no universal sample price that applies to every garment or manufacturer. Sampling cost depends on the amount of development work required and the materials used.

Common cost factors include:

Pattern creation and pattern revisions
Fabric sourcing and material minimums
Special linings and trims
Custom hardware
Printing, embroidery, or patches
Washing and finishing
Complex construction
Sample-making labor
Courier and shipping expenses
Additional revisions

A simple sample using available materials is usually less complicated to develop than a technical jacket requiring custom fabric, specialized trims, or extensive pattern work.

Ask the manufacturer to clarify what the sample quotation includes and whether further revisions will incur additional charges.

How to Estimate Your Sampling Budget

A useful planning formula is:

Estimated sampling budget = initial sample costs + expected revision costs + special material costs + shipping and testing costs.

For example, if a brand budgets for one prototype, one revised sample, and one final approval sample, it should estimate each stage separately instead of assuming all three will cost the same.

This is a budgeting method, not a universal pricing benchmark. Actual costs must be confirmed with the manufacturer.

How to Reduce Sample Costs Without Increasing Production Risk

The most effective way to control sample expenses is to reduce avoidable revisions.

Before requesting the first sample:

Prepare a clear technical pack where possible.
Confirm the intended fit and target measurements.
Select the preferred fabric and relevant alternatives.
Provide final or near-final artwork.
Identify the required trims and hardware.
Consolidate design feedback from all decision-makers.
Agree on the purpose of each sample round.

Avoid removing a necessary sample stage simply to reduce the initial development budget. A modest sampling expense may be preferable to discovering a major problem after bulk production begins.

How Long Does Clothing Sample Development Take?

What Affects the Clothing Sample Timeline?

The time required for clothing sample development depends on more than sewing time.

Important factors include:

How complete the initial design specifications are
Whether patterns already exist
Fabric and trim availability
Custom dyeing or washing requirements
Embroidery and print development
Sample-making capacity
Courier transit time
Time required for the buyer to review and approve each sample
The number and complexity of revisions

A simple garment using available materials may progress faster than a technical jacket requiring custom components.

The overall timeline should include both manufacturer working time and the time the brand needs to review each sample. A sample may be ready quickly but remain unapproved for days or weeks if feedback is delayed.

How to Build a Realistic Sampling Schedule

Plan the process backward from the intended bulk-production start date.

Allow time for:

Design and specification review.
Fabric and trim confirmation.
First sample development.
Shipping and internal review.
Fit corrections and revised sampling.
Final material and branding confirmation.
PP sample review and written approval.
Bulk-production preparation.

Do not assume that the bulk-production schedule begins automatically when the first sample is completed. The manufacturer may still need to source materials, confirm production capacity, prepare patterns, and arrange other components.

For seasonal collections, leave a buffer for unexpected material delays and sample revisions.

Clothing Sample Approval Checklist Before Bulk Production

Check the Garment Measurements and Fit

Compare the sample with the approved measurement chart.

Check the relevant points of measure, including body length, chest, shoulders, sleeves, armholes, waist, and hem. The exact measurements will depend on the garment.

Record the sample size, measurement results, and agreed tolerances. Confirm that the garment has been measured consistently.

Confirm Fabric, Color, and Trims

Verify that the sample uses the intended material or that any provisional substitutions are clearly documented.

Check the fabric composition, weight, hand feel, color, lining, zippers, buttons, snaps, drawcords, and other components relevant to the product.

If color accuracy is critical, establish the appropriate approved color reference rather than relying only on a photograph displayed on a screen.

Inspect Stitching and Construction

Review seam alignment, stitch consistency, reinforcement, edge finishing, pocket attachment, and other construction details.

For technical garments, verify that the construction matches the product's documented functional requirements.

A visually attractive sample is not necessarily a well-constructed sample. Inspect both appearance and function.

Approve Logos, Labels, and Packaging

Confirm logo dimensions, artwork, placement, color, embroidery or print quality, labels, care information, hangtags, and packaging.

If the brand uses custom packaging, make sure it is included in the production specification rather than discussed only in informal messages.

Confirm Any Required Testing

Where appropriate, specify tests for shrinkage, colorfastness, seam strength, abrasion, water resistance, or other relevant properties.

The required tests depend on the garment, its materials, its intended use, and any applicable market requirements.

For general quality-management context, consult ISO 9001 quality management systems. For apparel quality inspections that use acceptance sampling, see the ISO 2859-1 standard. A standard or certification does not replace product-specific testing or an agreed inspection plan.

Record Written Approval

Once the sample has passed review, document the approval.

The record should identify:

Product or style number
Sample type and version
Approval date
Approved measurements and tolerances
Fabric and trim specifications
Artwork and branding requirements
Outstanding exceptions, if any
Packaging requirements
Authorized approval contact

Where practical, retain an identified physical reference sample and keep the corresponding technical documents together.

The objective is to give both the brand and manufacturer the same definition of the approved product.

How to Reduce the Number of Sample Revisions

Prepare a Clear Tech Pack Before Sampling

A tech pack helps communicate how the garment should be manufactured.

Depending on the product, it can include technical drawings, measurements, construction details, fabric specifications, trim information, color references, artwork, label placement, and packaging requirements.

Not every project begins with a complete tech pack. However, the more clearly the requirements are documented, the less the manufacturer needs to guess.

Consolidate Feedback Into One Revision List

Avoid sending scattered changes across multiple messages without a single record of the latest requirements.

Instead, prepare one revision list with each issue, the current condition, the requested change, and the relevant measurement or reference.

For example:

Current sleeve length: 64 cm.
Requested sleeve length: 62 cm.
Measurement reference: sleeve length from the agreed shoulder point.
Required action: revise the pattern and confirm the next sample.

This makes the request more actionable than simply saying the sleeves are too long.

Separate Essential Changes From Optional Preferences

Not every change has the same importance.

Prioritize issues affecting fit, safety, function, required performance, construction, or compliance. Cosmetic preferences can be reviewed separately if they do not affect the core product requirements.

However, do not ignore branding or appearance requirements that are essential to the product's identity.

Freeze the Specifications Before Bulk Production

Once the final sample is approved, treat the relevant specifications as controlled production requirements.

Any subsequent change to fabric, measurements, trims, artwork, or construction should be documented and approved before it is implemented.

A verbal agreement to change one detail may create confusion if the manufacturer continues using an earlier technical pack or sample.

Assign One Person to Coordinate Sample Approval

For a brand with several founders, designers, or merchandising staff, appoint one person to consolidate feedback and communicate the final decision.

Conflicting comments from different team members can lead to unnecessary revisions and unclear approval records.

A single approval contact helps keep the sample development process organized.

Common Sample Approval Mistakes Clothing Brands Should Avoid

Approving a Sample Based Only on Photographs

Photographs can help review visual details, but they cannot fully establish fit, hand feel, construction quality, or performance.

Request a physical sample when those properties are important to the product.

Approving the Fit but Ignoring Final Materials

A garment may fit correctly in one fabric and behave differently in another.

If the material changes, evaluate whether the fit, drape, thickness, and construction still meet the intended requirements.

Assuming One Size Represents Every Size

A correct medium does not guarantee that the full size range is correct.

Use a size set when grading risk or customer fit expectations justify it.

Starting Bulk Production Before Final Approval

Beginning bulk production while key specifications remain unresolved can turn a small development issue into a large inventory problem.

Define the approval gate and make sure the responsible parties understand what must be confirmed before production starts.

Changing the Design After Sample Approval

Late changes can affect patterns, materials, costs, production schedules, and quality expectations.

If a change is necessary, assess its impact and document the revised requirements before the factory implements it.

Failing to Check Bulk Production Against the Approved Sample

Even a properly approved sample does not guarantee every bulk garment will be identical.

Use suitable in-line and final inspection procedures, and investigate deviations against the documented production standard.

From Product Concept to Approved Sample

JIMJACKETS provides private label and custom jacket manufacturing services for brands that need to develop products around their own specifications.

The process can begin with a technical pack, sketch, reference image, existing garment, or initial concept. The project requirements determine which development steps and sample stages are appropriate.

Explore the JIMJACKETS private label clothing manufacturer service for information about custom apparel development, sampling, branding, and bulk production.

Custom Jacket Samples for Fashion Brands

For brands developing outerwear, sampling may involve checking the silhouette, fit, materials, construction, hardware, pocket placement, branding, and finishing.

The required sample rounds depend on the complexity of the design and how many changes are needed before the product meets the agreed specifications.

JIMJACKETS also provides a dedicated guide on how to request custom jacket samples efficiently, which can help brands prepare their requirements before starting development.

Plan the Sampling Process Around Your Order

JIMJACKETS' current starting MOQ for jackets is 100 pieces per style per color, subject to confirmation for the specific product and materials.

A suitable sampling plan should be discussed alongside the proposed order quantity, fabric requirements, branding, target cost, and expected delivery schedule.

When requesting a quote, provide as much information as possible about the design, target fit, materials, colorways, size range, and intended use. If a complete tech pack is not available, start with your reference images and known requirements.

The goal is to determine the appropriate development stages before bulk production begins, rather than committing to an arbitrary number of sample rounds.

Frequently Asked Questions About Clothing Samples Before Bulk Production

How many samples should a clothing brand make before bulk production?

Many brands can plan around 2–4 sample rounds per style, but the exact number depends on design complexity, fit, materials, and specification readiness. Some established products need fewer rounds, while complex garments may need more. Approve all critical production requirements before bulk manufacturing.

Is one sample enough before placing a bulk clothing order?

One sample may be enough for a straightforward repeat product if its specifications are already established and the sample accurately represents the intended production version. For a new design, one sample may not be enough to verify fit, final materials, branding, and construction.

How many fit samples are needed for a new clothing brand?

A brand may need one fit sample and one revised fit sample, but the number depends on the corrections required. The important point is to verify the agreed measurements and fit rather than assuming a fixed number of samples will always be sufficient.

Do I need a pre-production sample after approving the fit sample?

A PP sample is advisable when final materials, trims, branding, construction, or other production details still need confirmation. If a previous sample already represents the complete intended production version, the manufacturer and buyer may agree on an appropriate approval procedure, but the production standard must still be clearly documented.

What is the difference between a prototype sample and a PP sample?

A prototype checks the initial design and construction feasibility. A PP sample verifies the final production version against the agreed specifications. The prototype may use provisional materials, while the PP sample should reflect the intended bulk materials and approved details wherever practical.

Should I make a size set sample before bulk production?

A size set is useful when a brand is introducing a new pattern, offering a broad size range, or needs greater confidence in grading accuracy. The scope may include selected sizes or a broader range depending on the garment and fit risks.

How much does a clothing sample cost?

Sample costs vary with garment complexity, pattern work, material availability, trims, decoration, shipping, and revisions. Ask the manufacturer for a breakdown of the initial sample fee, additional revision costs, special material charges, and shipping.

How long does it take to make clothing samples?

The timeline depends on design readiness, pattern development, material sourcing, production complexity, shipping, and buyer feedback. Ask the manufacturer to estimate each stage and include time for review and revisions rather than relying on sewing time alone.

Can I start bulk production while waiting for sample approval?

Starting bulk production before the required sample approval creates risk, especially if fit, materials, construction, or branding remain unresolved. If any preparatory work is authorized in advance, clearly identify what may proceed and who bears the risk if the final sample is rejected.

How do I avoid too many sample revisions?

Prepare a clear tech pack, confirm materials early, consolidate feedback, specify measurable corrections, and assign one person to coordinate approval. Each sample round should have a defined purpose and an agreed set of acceptance criteria.

What should I check before approving a clothing sample?

Check measurements, fit, fabric, color, construction, stitching, trims, hardware, branding, labels, finishing, and relevant performance requirements. Compare the sample against the written specifications and document the approval.

Does an approved sample guarantee bulk production quality?

No. An approved sample establishes a reference, but production consistency still depends on materials, workmanship, process controls, and inspection. Use the approved specifications as the basis for in-line and final quality checks.

How many samples should I make for a custom jacket collection?

For a new custom jacket, plan for the prototype, any necessary fit revisions, and a final production approval stage. A size set or additional technical samples may be needed for complex designs. Confirm the sampling plan with the manufacturer before development begins.

Final Recommendation: Approve the Right Samples, Not Just More Samples

For most new clothing styles, planning for 2–4 sample rounds is a useful starting point. The correct number depends on the product, the completeness of its specifications, the materials, the fit requirements, and the level of technical risk.

A prototype helps validate the design. Fit sampling resolves measurement and proportion issues. A size set checks grading when necessary. A pre-production sample confirms the intended production version before bulk manufacturing.

The most efficient sampling process is one in which every round answers a specific question and every approval is documented.

Before placing your next bulk clothing order, make sure the final sample, specifications, and quality requirements are aligned. If you are developing a custom jacket collection, visit JIMJACKETS to discuss your product concept, sample requirements, and bulk production plan.
