Before a clothing brand places a large fabric order, there is usually an important step between fabric selection and bulk production: fabric approval.
Fabric approval is the process of checking and confirming that a fabric meets the brand's requirements before it is used for bulk garment production.
For clothing brands, garment manufacturers and wholesale buyers, this process can help reduce problems related to GSM, DIA, colour, fabric construction, shrinkage, stretch, printing and finished garment appearance.
A fabric may look good in a photograph or catalogue, but the actual sample needs to be evaluated before a buyer commits to a larger quantity.
In this guide, we explain how the fabric approval process works between brands and fabric suppliers, what buyers should check, and what should be confirmed before bulk production begins.
What Is Fabric Approval?
Fabric approval is the process of evaluating a fabric sample against the requirements of a clothing brand or garment manufacturer and confirming that it is suitable for production.
The approval process can include checking:
- Fabric type
- Composition
- GSM
- DIA or usable width
- Fabric construction
- Colour and shade
- Fabric feel
- Stretch and recovery
- Shrinkage
- Printing compatibility
- Surface quality
- Finished garment appearance
The exact checks depend on the garment, fabric and production requirements.

Why Is Fabric Approval Important?
A fabric sample may appear suitable when viewed as a loose piece of material, but its behaviour can change during cutting, stitching, printing, washing and finishing.
Approving the fabric before bulk production gives the brand an opportunity to evaluate the actual material before committing to a large quantity.
This can help identify potential issues related to:
- Incorrect GSM
- Incorrect DIA or width
- Colour variation
- Uneven construction
- Unexpected shrinkage
- Insufficient stretch recovery
- Printing problems
- Surface defects
- Unexpected garment appearance
Our guide on Common Fabric Problems During Garment Production explains several quality issues that buyers should consider before production.
Who Is Involved in Fabric Approval?
Depending on the business, several people may be involved in the fabric approval process.
- Clothing brand or product development team
- Fabric buyer or sourcing team
- Garment manufacturer
- Fabric supplier
- Quality-control team
- Printing or production team
For smaller clothing brands, one person may handle several of these responsibilities.
For larger businesses, fabric sourcing, quality control and product development may be handled by separate teams.
Step 1: The Brand Defines the Fabric Requirement
Fabric approval should begin with a clear understanding of what the brand wants to manufacture.
Before contacting a supplier, the buyer should define the basic requirements.
Important Fabric Requirements
- Fabric type
- Composition
- GSM
- DIA or width
- Construction
- Colour
- Finish
- Stretch requirement
- Garment application
- Printing requirement
For example, the requirements for a running T-shirt may be different from those for a cricket jersey, gym T-shirt or athleisure garment.
Our article How to Choose the Right Sportswear Fabric for Your Target Customer explains how customer activity, climate and garment application can influence fabric selection.
Step 2: The Supplier Provides a Fabric Sample
Once the requirements are understood, the supplier can provide a suitable fabric sample for evaluation.
The sample gives the buyer an opportunity to physically inspect the material instead of making a decision based only on a product name or photograph.
During this stage, the buyer should record important information about the sample, such as:
- Fabric name
- Supplier reference
- Colour
- GSM
- DIA or width
- Construction
- Sample date
Keeping a clear sample reference becomes particularly useful when a brand develops several fabrics or colours at the same time.
Step 3: Check the Fabric Specification
The next stage is to compare the actual fabric against the required specification.
GSM
GSM refers to the approximate weight of the fabric in grams per square metre.
The buyer should confirm that the fabric weight is appropriate for the intended garment.
Read our Complete Guide to Fabric GSM for more information about GSM and fabric selection.
DIA and Width
For knitted fabrics, DIA or usable width can affect pattern placement, fabric consumption and cutting efficiency.
The buyer should confirm that the fabric dimensions are suitable for the garment being developed.

Step 4: Check Fabric Appearance and Hand Feel
Technical specifications are important, but buyers should also physically evaluate the fabric.
Check:
- Surface appearance
- Texture
- Softness
- Hand feel
- Drape
- Fabric body
- Surface uniformity
- Overall appearance
Two fabrics can have similar GSM and still feel or look different because of differences in construction, yarn, finishing and surface structure.
This is particularly important for brands positioning their garments as premium products.
Step 5: Check Colour and Shade
Colour approval is particularly important for brands producing fashion collections, uniforms, teamwear and repeat orders.
The buyer should compare the fabric sample against the approved colour reference.
Check for:
- Correct colour
- Shade consistency
- Surface colour uniformity
- Roll-to-roll consistency where applicable
- Compatibility with the final garment design
Colour consistency becomes even more important when the same fabric will be reordered for future production.
Step 6: Test Stretch and Recovery When Required
Stretch performance should be checked when the fabric is intended for fitted garments, gymwear, activewear or other products where movement is important.
The buyer should evaluate:
- Amount of stretch
- Direction of stretch
- Recovery after stretching
- Comfort during movement
- Behaviour after repeated stretching
More stretch is not automatically better. The required stretch depends on the garment design and intended use.
Step 7: Test Shrinkage and Wash Performance
A fabric can look correct before washing but behave differently after washing.
Where relevant, the buyer should test:
- Dimensional change
- Colour after washing
- Surface appearance
- Shape stability
- Stretch recovery
Testing the fabric before bulk production can help identify potential problems before a large quantity is converted into garments.

Step 8: Test Printing When Required
For printed sportswear, jerseys, uniforms and custom apparel, the fabric should be tested with the intended printing process before bulk production.
Check:
- Print clarity
- Colour appearance
- Surface compatibility
- Print coverage
- Print durability
- Finished garment appearance
A fabric may look suitable as a plain sample but produce a different result after printing.
For sportswear brands, printing compatibility should therefore be considered during fabric approval rather than after bulk fabric has already been purchased.
Step 9: Make a Sample Garment
One of the most useful stages of fabric approval is converting the approved fabric into an actual garment sample.
The finished sample allows the brand to evaluate how the fabric behaves during real garment production.
Check:
- Fit
- Drape
- Garment appearance
- Stitching behaviour
- Print quality
- Comfort
- Fabric stretch
- Overall construction
A fabric can look excellent as a roll but behave differently after cutting, stitching and finishing.
Our guide From Fabric Roll to Finished Garment: Complete Apparel Manufacturing Process explains how fabric moves through inspection, cutting, stitching, printing, finishing and quality checking.
Step 10: Compare the Sample With the Original Requirement
After testing the fabric and making a sample garment, compare the results with the original product requirement.
| Requirement | What to Check |
|---|---|
| Fabric type | Does the construction match? |
| GSM | Is the fabric weight suitable? |
| DIA / Width | Is it suitable for cutting? |
| Colour | Does the shade match the approved reference? |
| Stretch | Does it provide the required movement? |
| Recovery | Does the fabric return toward its original shape as required? |
| Shrinkage | Is dimensional stability suitable? |
| Printing | Does the intended print process work correctly? |
| Appearance | Does the finished garment look as intended? |
Step 11: Approve, Reject or Request Changes
After evaluation, the brand can make a clear decision about the fabric.
Approved
The fabric meets the required specifications and performs appropriately for the intended garment.
Approved With Changes
The fabric is close to the requirement but needs an adjustment, such as colour, GSM, DIA, finish or another specification.
Rejected
The fabric does not meet the requirements and another option or new sample is required.
If changes are requested, the supplier can provide another sample for evaluation before the bulk order is confirmed.
Step 12: Record the Approved Fabric Specification
Once the fabric has been approved, the brand should keep a clear record of the approved specification.
The record can include:
- Fabric name
- Composition
- GSM
- DIA or width
- Construction
- Colour reference
- Finish
- Stretch requirement
- Printing requirement
- Approved sample reference
- Date of approval
This approved reference can then be used when discussing the bulk order and future repeat production.
Step 13: Confirm MOQ, Price and Lead Time
After technical approval, the commercial details should also be confirmed before placing the bulk order.
Discuss:
- Price
- MOQ
- Available quantity
- Colour availability
- Production lead time
- Dispatch requirements
- Repeat-order availability
For buyers starting with smaller production quantities, MOQ can be particularly important.
Read: What Is MOQ in Fabric Buying and Why Does It Matter? .
At Walrus – Yes India Can, lower MOQ options are available on selected polyester fabrics. Buyers can discuss their actual quantity requirements with the team and check suitable options based on the fabric, colour and production requirement.
Step 14: Confirm the Bulk Fabric Matches the Approved Sample
Fabric approval should not end when the sample is approved.
When the bulk fabric is supplied, buyers should compare it with the approved reference.
Important checks can include:
- GSM consistency
- DIA or width consistency
- Colour consistency
- Construction consistency
- Surface appearance
- Fabric feel
- Finish
This is particularly important for brands that intend to reorder the same fabric in the future.
Our Fabric Buyer's Scorecard provides a structured way to evaluate quality, GSM, DIA, finish, performance, price and supplier reliability.
Fabric Approval Process: A Simple Workflow
The complete process can be summarized as:
Requirement → Supplier Sample → Specification Check → Fabric Testing → Garment Sample → Review → Approval → Commercial Confirmation → Bulk Order → Bulk Quality Check
Keeping this process organized can make communication between the brand and supplier much clearer.
Common Fabric Approval Mistakes
1. Approving From a Photograph Alone
A photograph cannot show every aspect of fabric feel, stretch, surface quality or finished-garment behaviour.
2. Checking Only GSM
GSM is important, but fabric performance also depends on construction, yarn, finishing and intended application.
3. Skipping the Garment Sample
A fabric should ideally be evaluated as part of the actual garment before committing to large production.
4. Ignoring Colour Consistency
Colour differences can become highly visible in finished garments, especially for teamwear and branded collections.
5. Not Recording the Approved Specification
Without a clear reference, it can become difficult to communicate the exact requirement for repeat production.
6. Comparing Only the Price
A lower price does not necessarily mean better overall value.
Buyers should consider quality, GSM, DIA, construction, performance, consumption, consistency and supplier reliability together.

Final Thoughts
Fabric approval is an important link between fabric sourcing and bulk garment production.
Instead of selecting a fabric and immediately placing a large order, brands can follow a structured process:
Define the requirement → Evaluate the sample → Test the fabric → Develop the garment sample → Approve the specification → Confirm commercial terms → Check bulk consistency
This approach gives clothing brands and garment manufacturers a clearer way to evaluate fabric before committing to bulk production.
