Before a clothing brand approves bulk production, the garment usually goes through several sampling stages.

These samples help the brand and manufacturer check whether the design, fit, measurements, fabric, trims, printing, stitching, and overall construction are correct.

For new clothing brands, garment sampling can feel confusing because factories may use terms such as:

• Proto sample

• Fit sample

• Size set sample

• Pre-production sample

• Salesman sample

• TOP sample

Each sample has a different purpose.

Understanding these stages can help brands avoid production mistakes, improve garment quality, and communicate more clearly with manufacturers.

This guide explains the main garment sampling stages, with special focus on proto, fit, size set, and pre-production samples.

What Is Garment Sampling?

Garment sampling is the process of creating sample garments before bulk production begins.

The purpose is to test and approve different aspects of the product.

Depending on the stage, a sample may be used to check:

• Design

• Fit

• Measurements

• Fabric

• Colour

• Trims

• Construction

• Printing

• Embroidery

• Labels

• Packaging

• Size grading

Sampling acts as a control process between design and mass production.

Instead of discovering a mistake after producing 1,000 garments, brands can identify problems while making only a few samples.

Why Garment Sampling Is Important

Sampling helps reduce production risk.

A garment may look correct on paper but behave differently once it is actually stitched.

For example, a sample may reveal that:

• The neckline is too wide

• The sleeve is too short

• The chest is too tight

• The fabric stretches too much

• The print is positioned incorrectly

• The zipper is too heavy

• The fabric colour does not match the approved shade

• The garment shrinks after washing

• The larger sizes do not look proportional

Finding these issues early is much less expensive than correcting them after bulk production.

Main Garment Sampling Stages

The exact sampling process varies by brand and manufacturer.

However, a common development flow is:

Design / Tech Pack → Proto Sample → Fit Sample → Size Set Sample → Pre-Production Sample → Bulk Production

Some companies may combine certain stages or use additional samples.

Let us understand each one.

1. Proto Sample

A proto sample, short for prototype sample, is usually one of the first physical versions of the garment.

Its purpose is to convert the design idea into an actual garment.

At this stage, the sample may not use the final fabric, trims, or colours.

The main objective is usually to understand the overall design and construction.

What Is Checked in a Proto Sample?

A proto sample may be used to review:

• Overall silhouette

• Design proportion

• Garment shape

• Panel placement

• Pocket position

• Sleeve shape

• Hood shape

• Basic construction

• General measurements

For example, if a brand is developing an oversized hoodie, the proto sample helps answer questions such as:

• Is the body wide enough?

• Is the shoulder drop correct?

• Is the hood proportion appropriate?

• Are the pockets positioned correctly?

• Does the garment look like the intended design?

Does a Proto Sample Use Final Fabric?

Not always.

A proto sample may sometimes use an available substitute fabric if the final production fabric has not yet been sourced.

However, if fabric behaviour strongly affects the garment, using something similar to the intended material is better.

For example, a stretch activewear garment should ideally be tested using a fabric with similar stretch and recovery.

2. Fit Sample

Once the basic design is approved, the next major stage is usually the fit sample.

The fit sample focuses primarily on how the garment fits the intended wearer.

It is usually developed in a base size such as Medium.

What Is Checked in a Fit Sample?

The brand may check:

• Chest fit

• Waist fit

• Hip fit

• Shoulder position

• Sleeve length

• Body length

• Armhole

• Neck opening

• Mobility

• Overall balance

• Garment ease

The sample is often worn by a fit model or person whose measurements closely match the target base size.

Why Fit Samples Matter

A garment can meet the written measurements and still feel uncomfortable.

Fit testing helps evaluate the garment in real use.

For example:

A T-shirt may measure correctly when laid flat but still feel tight around the armhole.

A pair of joggers may have the correct waist measurement but restrict movement around the thigh.

That is why physical fit evaluation is important.

Base Size in Fit Sampling

Most brands select one base size for fit development.

For example:

• Women's top: M

• Men's T-shirt: M or L

• Kidswear: Selected age reference

The base size is perfected first.

Once the fit is approved, the pattern is graded into other sizes.

What Happens After a Fit Sample Is Reviewed?

The brand or technical team records comments.

For example:

• Increase body length by 2 cm

• Reduce chest width by 1 cm

• Increase sleeve length by 1.5 cm

• Raise neckline by 0.5 cm

• Reduce armhole depth

• Move pocket 2 cm upward

The manufacturer or pattern maker updates the pattern.

Another fit sample may then be produced.

Several fit rounds may be required before approval.

3. Size Set Sample

Once the base size is approved and grading is completed, the manufacturer may prepare a size set sample.

A size set contains samples in multiple sizes.

For example:

S, M, L, XL, XXL

The purpose is to check whether the garment remains properly proportioned across all sizes.

Why Size Set Samples Are Important

Pattern grading does not always work perfectly.

A size may become too wide, too long, or badly proportioned if the grade rules are incorrect.

For example:

• XXL sleeves may become too long

• Small size neckline may become too tight

• XL shoulders may become excessively wide

• Garment length may increase too quickly

Size set sampling helps identify these problems before bulk production.

What Is Checked in a Size Set?

Typical checks include:

• Graded measurements

• Fit progression

• Proportion

• Sleeve grading

• Body length grading

• Neck grading

• Shoulder grading

• Visual consistency

The technical team may measure every sample against the graded specification sheet.

Do All Sizes Need to Be Sampled?

Not always.

Some manufacturers may produce every size.

Others may sample key sizes only.

For example:

S, L, and XXL

This depends on:

• Product complexity

• Order value

• Brand requirements

• Size range

• Production risk

For a new style, a full size set may provide more confidence.

4. Pre-Production Sample

The pre-production sample, often called a PP sample, is one of the most important samples before bulk manufacturing.

This sample should closely represent the final product.

It is usually made using approved production materials.

What Should Be Included in a Pre-Production Sample?

Ideally, the PP sample should include:

• Final fabric

• Approved colour

• Final trims

• Final stitching

• Final labels

• Final print or embroidery

• Final measurements

• Final construction

• Final finishing

The goal is to create a reference garment that represents what the bulk order should look like.

Why Is the PP Sample Important?

The PP sample serves as a final checkpoint.

Before production begins, the brand can confirm:

• Correct fabric

• Correct colour

• Correct fit

• Correct labels

• Correct trims

• Correct logo placement

• Correct print quality

• Correct construction

Once approved, bulk production should follow the PP sample and final tech pack.

Approved PP Sample as Production Reference

An approved PP sample may be physically signed, sealed, tagged, or documented.

The manufacturer can keep one approved sample on the production floor or in the quality department.

Quality inspectors can compare bulk garments against this reference.

This helps maintain consistency.

Proto vs Fit vs Size Set vs PP Sample

Here is a simple comparison:

Sample Type	Main Purpose	Typical Focus
Proto Sample	Test initial design	Shape, construction, silhouette
Fit Sample	Test fit	Measurements, comfort, balance
Size Set Sample	Test grading	Proportion across sizes
Pre-Production Sample	Final approval	Complete production-ready garment

Each stage answers a different question.

Proto Sample: “Does the Design Work?”

The proto stage focuses on turning the idea into a garment.

Main question:

Does the design look and function as intended?

Fit Sample: “Does the Garment Fit Correctly?”

Main question:

Does the base size fit the intended customer properly?

Size Set Sample: “Do All Sizes Work?”

Main question:

Has the approved base size been graded correctly into smaller and larger sizes?

Pre-Production Sample: “Is Everything Ready for Bulk Production?”

Main question:

Is this the exact garment we are ready to manufacture in bulk?

What Is a Salesman Sample?

Some brands also use a salesman sample.

It is usually made to present the collection to:

• Buyers

• Retailers

• Distributors

• Sales teams

Salesman samples may be created before bulk production so orders can be collected.

They are often visually close to the final product.

What Is a Photoshoot Sample?

A photoshoot sample is prepared for:

• Product photography

• Campaigns

• E-commerce

• Social media

• Catalogues

It should represent the product accurately because customers will see it before purchasing.

What Is a TOP Sample?

TOP stands for Top of Production.

A TOP sample is taken from the early bulk production run.

Its purpose is to confirm that production matches the approved standard.

This is different from the PP sample because the PP sample is made before bulk production.

The TOP sample comes from actual production.

What Is a Shipment Sample?

A shipment sample is selected from completed production before dispatch.

It can be used as a final reference for:

• Quality

• Packaging

• Labelling

• Colour

• Measurements

Some buyers require shipment samples before goods are released.

Garment Sampling Workflow Example

Imagine a brand wants to produce a new oversized T-shirt.

The process may look like this:

Step 1: Tech Pack Created

The brand provides:

• Sketch

• Measurements

• Fabric

• Print

• Colour

• Labels

Step 2: Proto Sample

The manufacturer creates the first physical version.

The brand checks silhouette and construction.

Step 3: Fit Sample

The garment is corrected and tested on a fit model.

Fit adjustments are made.

Step 4: Size Set

S, M, L, XL, and XXL samples are checked.

Grading errors are corrected.

Step 5: PP Sample

The final sample is made using approved fabric, print, labels, and packaging details.

Step 6: Approval

The brand approves the PP sample.

Step 7: Bulk Production

Factory begins manufacturing.

How Long Does Garment Sampling Take?

There is no universal timeline.

Sampling depends on:

• Garment complexity

• Fabric availability

• Trim availability

• Factory workload

• Number of corrections

• Print development

• Pattern changes

A simple T-shirt may move faster than a complex jacket.

The sampling process can take longer if:

• Fabric is unavailable

• Colours need lab dip approval

• Custom trims are required

• Fit needs multiple corrections

Brands should include sampling time in their launch plan.

How Much Does Garment Sampling Cost?

Sample cost depends on:

• Garment complexity

• Fabric

• Trims

• Pattern development

• Printing

• Labour

• Quantity

A sample can cost more per piece than bulk production because it is produced individually.

Some factories may charge:

• Sample fee

• Pattern fee

• Printing setup

• Courier cost

Some may adjust certain charges against bulk orders.

Always confirm the sample policy before development begins.

What Information Should Be Sent Before Sampling?

A manufacturer can create better samples when the brand provides clear information.

A good sample request may include:

• Tech pack

• Front and back sketch

• Measurement specification

• Fabric details

• Colour reference

• Print artwork

• Label artwork

• Trim details

• Construction notes

• Fit reference

Incomplete information can lead to unnecessary sample rounds.

Sample Approval Comments

When reviewing a sample, avoid vague feedback.

Instead of:

Make it slightly better.

Use measurable comments such as:

• Increase sleeve length by 1 cm

• Reduce neckline width by 0.5 cm

• Move chest logo 2 cm upward

• Increase bottom opening by 2 cm

• Change drawcord length to 120 cm

Clear comments help factories make accurate corrections.

Keep a Sample Comment Sheet

Professional brands often maintain a sample comment sheet.

It may include:

• Sample stage

• Date

• Measurement issue

• Construction issue

• Correction required

• Approval status

Example:

Area	Current	Required	Comment
Body Length	68 cm	70 cm	Increase 2 cm
Sleeve Length	21 cm	22 cm	Increase 1 cm
Chest Width	54 cm	53 cm	Reduce 1 cm

This creates a clear technical record.

Why Fabric Should Be Tested During Sampling

Garment fit can change because of fabric behaviour.

Important characteristics include:

• Stretch

• Recovery

• Shrinkage

• GSM

• Drape

• Thickness

• Surface finish

A pattern that fits well in one fabric may not fit the same way in another fabric.

For this reason, the later sampling stages should ideally use the actual production fabric.

Washing and Shrinkage Tests

If the garment is washable, sample testing should consider shrinkage.

For example:

Initial garment length: 72 cm

After wash: 70 cm

That 2 cm change may affect fit.

Brands should understand whether the garment meets the final measurement requirement:

• Before wash

• After wash

• After finishing

The measurement standard should be clearly defined.

Printing and Embroidery During Sampling

Print and embroidery should also be checked before bulk production.

Review:

• Artwork size

• Placement

• Colour

• Registration

• Print feel

• Embroidery density

• Thread colour

Even a small placement error can change the appearance of the final garment.

Trim Approval During Sampling

Trims should be checked for:

• Size

• Colour

• Function

• Durability

• Appearance

Examples include:

• Zippers

• Buttons

• Drawcords

• Elastic

• Eyelets

• Snaps

A low-quality zipper can create customer complaints even if the garment fabric is excellent.

Label Approval During Sampling

Final samples should verify label details such as:

• Brand label

• Size label

• Care label

• Composition

• Country of origin

Also check placement.

For example:

• Main label at back neck

• Size label below main label

• Care label at side seam

Incorrect labels can cause compliance or customer-service problems.

Packaging Approval

Packaging may also need approval before production is dispatched.

Check:

• Folding method

• Polybag size

• Barcode

• Size sticker

• Hang tag

• Carton packing

This is particularly important for retail and marketplace orders.

Common Sampling Mistakes New Clothing Brands Make

1. Skipping Proto or Fit Stages

Moving too quickly to production increases risk.

2. Approving Samples Without Measuring Them

Do not judge samples only by appearance.

Check measurements against the spec sheet.

3. Using Different Fabric for Final Approval

A final sample should ideally represent the production fabric.

4. Making Verbal Changes Only

Document every correction.

5. Ignoring Large and Small Sizes

Grading problems may only appear at size extremes.

6. Approving Prints Without Checking Placement

Always measure print location.

7. Rushing PP Approval

Do not approve a PP sample simply because the production deadline is close.

Can Some Sampling Stages Be Combined?

Yes.

For simple products, a manufacturer may combine stages.

For example:

A basic standard T-shirt may move from fit sample directly to PP sample.

However, more complex garments generally require more thorough sampling.

Combining stages should depend on risk, not only speed.

How Many Sample Rounds Are Normal?

There is no fixed number.

Some products are approved after one or two rounds.

Others require several revisions.

The number of rounds depends on:

• Design complexity

• Accuracy of tech pack

• Manufacturer experience

• Pattern quality

• Fabric

• Communication

Clear specifications usually reduce unnecessary sampling.

Sample Approval Checklist

Before approving a garment sample, check:

• Design

• Fit

• Measurements

• Fabric

• Colour

• Shrinkage

• Stitching

• Seams

• Trims

• Labels

• Print

• Embroidery

• Size grading

• Packaging

Do not focus only on visual appearance.

Why Sampling Saves Money

Sampling may feel like an extra expense.

In reality, it can prevent much larger losses.

Imagine producing 2,000 garments with:

• Wrong sleeve length

• Poor print placement

• Incorrect size grading

Correcting that mistake after production can be extremely expensive.

Producing a few samples first is much safer.

Sampling and Quality Control

Sampling establishes the standard that quality control teams can follow.

An approved sample helps inspectors judge:

• Measurements

• Construction

• Fabric

• Colour

• Workmanship

• Packaging

Without an approved reference, quality decisions can become subjective.

Garment Sampling for Small Brands

Small brands sometimes believe they can skip sampling because their order is small.

This is risky.

A small brand may be even more affected by mistakes because it has less capital available.

Even for low quantities, at least one properly reviewed sample is strongly recommended.

Simple Sampling Process for New Brands

If you are starting a new clothing brand, use this practical workflow:

1. Prepare design and tech pack

2. Develop proto sample

3. Review design

4. Develop fit sample

5. Approve fit

6. Grade the pattern

7. Check size set

8. Produce PP sample

9. Approve final materials and construction

10. Begin bulk production

This creates a controlled path from idea to finished product.

Frequently Asked Questions

What is a proto sample?

A proto sample is an early physical version of the garment used to test design, shape, and construction.

What is a fit sample?

A fit sample is used to evaluate how the garment fits the intended wearer, usually in a base size.

What is a size set sample?

A size set contains samples in multiple sizes to check whether grading and proportions are correct.

What is a pre-production sample?

A pre-production or PP sample is the final approval sample made before bulk manufacturing, ideally using production materials and construction.

Is the PP sample the same as a TOP sample?

No.

The PP sample is made before bulk production.

The TOP sample is selected from the beginning of actual production.

Can I skip the size set sample?

For simple products, some brands may skip or reduce the size set stage.

However, size-set checking is useful when introducing a new style or grading system.

How many fit samples are required?

There is no fixed number.

Sampling continues until the fit is approved.

Should I approve samples through photos only?

Photos can help with communication, but physical measurement, fit, fabric feel, and workmanship are difficult to judge accurately through images alone.

For important approvals, a physical sample is preferable.

Final Thoughts

Garment sampling is one of the most important stages between product design and bulk manufacturing.

Each sample has a specific purpose.

The proto sample checks whether the initial design works.

The fit sample checks whether the garment fits correctly.

The size set sample checks whether grading works across different sizes.

The pre-production sample confirms that the final fabric, trims, construction, labels, artwork, and measurements are ready for bulk production.

Skipping these stages can save time initially, but it can create much larger problems later.

For clothing brands, the safest approach is to treat sampling as part of product development—not as an unnecessary expense.

A well-approved sample gives both the brand and the manufacturer a clear production standard.

Good sampling leads to better fit, better quality, fewer mistakes, and more consistent garments.
