Choosing fabric is one of the most important decisions when developing a clothing collection.
A garment's appearance, comfort, fit, durability and production cost are all influenced by the fabric. Even a well-designed garment can produce disappointing results if the material is unsuitable for the product.
For clothing brands, fabric sourcing therefore involves more than finding a supplier with an attractive price.
Brands need to define the required material, understand fabric specifications, evaluate samples, consider minimum order quantities, test the fabric where necessary and determine whether the supplier can provide consistent material for future production.
A structured sourcing process can reduce costly mistakes before garment production begins.
Brands can browse textile companies on TurkishTextile.org to discover fabric manufacturers and suppliers from different countries.
Start With the Garment
Do not begin by asking:
What fabrics do you have?
Start with the garment you want to manufacture.
Consider:
- What type of garment is it?
- How should it fit?
- Should it be lightweight or heavy?
- Does it need stretch?
- Should it feel soft or structured?
- Is breathability important?
- How should it drape?
- How will the garment be washed?
- In which season will it be worn?
A fabric suitable for an oversized sweatshirt is very different from one intended for leggings, a summer dress or a structured jacket.
The garment should determine the fabric requirement rather than the other way around.
Understand Fabric Composition
Fabric composition identifies the fibers used in the material.
Common examples include:
- 100% cotton
- 100% polyester
- 100% viscose
- Cotton/polyester
- Cotton/elastane
- Polyester/elastane
- Viscose/elastane
- Wool blends
- Linen blends
- Polyamide/elastane
Different fibers provide different characteristics.
Cotton is widely used in casual apparel, while elastane may be added when stretch and recovery are required. Polyester, viscose, linen, wool and polyamide each have characteristics suitable for different applications.
There is no single "best" composition.
The correct choice depends on the garment being developed.
Choose Between Knitted and Woven Fabric
Most clothing fabrics can broadly be divided into knitted and woven constructions.
Knitted Fabrics
Common examples include:
- Single jersey
- Rib
- Interlock
- Piqué
- French terry
- Fleece
Knitted fabrics are commonly used for products such as:
- T-shirts
- Sweatshirts
- Hoodies
- Sportswear
- Underwear
- Leggings
Woven Fabrics
Examples include:
- Poplin
- Twill
- Denim
- Gabardine
- Satin
- Canvas
They are commonly used for:
- Shirts
- Trousers
- Dresses
- Jackets
- Jeans
- Workwear
Construction affects stretch, appearance, drape and garment manufacturing.
A brand should therefore define both the fiber composition and fabric construction.
Understand GSM
GSM means grams per square meter and describes fabric weight.
For example:
100% cotton single jersey — 180 GSM
and:
100% cotton single jersey — 240 GSM
are both cotton single jersey fabrics, but they can produce substantially different garments.
Fabric weight affects factors such as:
- Garment weight
- Drape
- Opacity
- Warmth
- Structure
- Hand feel
Do not choose GSM from a generic internet chart alone.
The appropriate weight depends on the actual fabric construction, finishing and garment design.
Use Reference Garments
If you are developing a product and do not yet understand textile terminology, a physical reference garment can be useful.
For example, you may have a T-shirt whose:
- Weight
- Thickness
- Surface
- Stretch
- Drape
- Softness
are close to what you want.
A reference garment does not replace a technical specification, but it can help communicate the intended result to manufacturers and fabric suppliers.
The next step is to identify the technical characteristics needed to reproduce the desired performance.
Create a Fabric Specification
Before requesting quotations, prepare a basic specification.
For example:
Product: Oversized T-shirt
Fabric: Single jersey
Composition: 100% cotton
Weight: 220 GSM
Width: Minimum 180 cm usable width
Colors: Black, white and navy
Finish: Soft hand feel
Quantity: 500 kg per color
For activewear:
Fabric: Knitted performance fabric
Composition: 75% polyamide / 25% elastane
Weight: approximately 220 GSM
Requirement: four-way stretch and good recovery
Colors: Black and navy
The specification does not have to contain unnecessary technical details.
It should contain the details that actually matter to the finished garment.
Decide Whether You Need Stock Fabric or Custom Production
A clothing brand may source fabric in two main ways.
Ready-Stock Fabric
The fabric already exists and is available for purchase.
This can be useful for:
- Small collections
- Sampling
- Lower quantities
- Faster production
- Testing a new product
However, future availability may be uncertain.
Brands can browse textile classifieds to discover ready-stock and surplus textile materials.
Custom Production
The fabric is manufactured according to the order.
This may provide more control over:
- Composition
- GSM
- Color
- Finishing
- Performance
But custom production can involve higher MOQs and longer lead times.
The appropriate choice depends on the brand's quantity, budget and need for repeatability.
Understand Fabric MOQ
Fabric MOQ can become one of the biggest challenges for smaller clothing brands.
A mill may have a minimum quantity for:
- Fabric construction
- Color
- Dye lot
- Finish
For example:
MOQ: 500 kg per color.
If your collection uses four colors, the fabric requirement could become 2,000 kg.
This may be far more material than a new brand needs.
Ask suppliers:
What is the MOQ for this fabric?
Is the MOQ per color?
Are standard colors available from stock?
Can smaller quantities be purchased at a higher price?
Using existing stock fabric can sometimes make smaller garment production possible.
Limit Colors in Small Collections
Every additional color can increase complexity.
A collection with:
1 style × 2 colors
is much easier to produce in small quantities than:
1 style × 10 colors.
Additional colors can affect:
- Fabric MOQ
- Dyeing
- Cutting
- Inventory
- Garment MOQ
- Production planning
For a first collection, concentrating volume into fewer colors may provide greater flexibility.
Request Fabric Swatches
Never select important fabric solely from a written description.
Ask for swatches where possible.
A swatch allows you to examine:
- Color
- Texture
- Surface
- Stretch
- Thickness
- Hand feel
- Drape
However, remember that a small swatch may not reveal every characteristic of the material.
If the fabric is important to the garment's performance, the next stage should be testing it in an actual sample garment.
Make a Garment Sample
A fabric can look excellent as a swatch but behave differently after it is cut and sewn.
Producing a sample garment helps evaluate:
- Fit
- Drape
- Stretch
- Opacity
- Structure
- Sewing performance
- Overall appearance
For example, a fabric that appears suitable for an oversized T-shirt may turn out to be too stiff once the complete garment is produced.
This is why fabric approval and garment sampling should work together.
Wash the Sample
Many problems become visible only after washing.
Depending on the product, check:
- Shrinkage
- Twisting
- Color change
- Pilling
- Surface appearance
- Stretch recovery
- Garment measurements
A T-shirt that looks correct before washing but changes significantly afterward can create returns and customer dissatisfaction.
Where wash performance matters, evaluate it before approving bulk production.
Consider Fabric Testing
For larger production runs or products with specific performance requirements, laboratory testing may be appropriate.
Relevant tests can include:
- Fiber composition
- GSM
- Shrinkage
- Color fastness
- Pilling
- Abrasion
- Stretch and recovery
- Dimensional stability
The required tests depend on the product.
An everyday T-shirt and technical sportswear do not necessarily require the same testing program.
Check Color Consistency
Color consistency becomes important when fabric is produced in different dye lots.
Two batches using the same color reference may still show slight shade differences.
Ask whether your production quantity will come from:
- One dye lot
- Several dye lots
For repeat garment orders, discuss how the supplier manages color consistency between production batches.
This can become especially important for permanent products that remain in a brand's collection over several seasons.
Consider Shrinkage Before Finalizing Measurements
Fabric shrinkage can affect garment dimensions.
If fabric changes during washing or finishing, the final garment may no longer match the intended measurements.
Garment manufacturers normally need to consider expected shrinkage when developing patterns and production specifications.
For brands, the important point is to establish the fabric's behavior before bulk production, rather than discovering it after finished garments have been produced.
Think About Repeat Orders
A fabric may be perfect for the first collection but unsuitable for the business model if it cannot be sourced again.
Ask:
Is this a regular production fabric?
Can you reproduce this color?
What is the normal lead time for repeat orders?
Is the specification expected to remain available?
This distinction is particularly important when comparing regular production fabric with deadstock.
Deadstock can be excellent for limited collections, but a brand should not assume that exactly the same material will be available later.
Consider Certification Requirements
Depending on the brand, product and target market, particular certifications may be required.
Examples encountered in textile sourcing can include requirements relating to:
- Textile safety
- Organic fibers
- Recycled materials
- Chemical management
- Traceability
If a certification is important to your brand or customer, communicate the requirement before ordering.
Also verify the actual documentation rather than relying only on a supplier's marketing statements.
Calculate Fabric Cost Per Garment
Fabric price per meter or kilogram does not directly tell you the material cost of one garment.
Garment cost also depends on:
- Fabric width
- Fabric weight
- Pattern
- Size
- Cutting efficiency
- Waste
- Shrinkage
A wider fabric with a slightly higher price may sometimes produce a lower garment cost because the pattern can be placed more efficiently.
Therefore, compare fabric consumption per garment, not only fabric price.
Do Not Choose a Supplier on Price Alone
Suppose one supplier quotes $4.00/kg and another quotes $4.30/kg.
The first offer is not automatically cheaper in practice.
Differences could exist in:
- Usable width
- GSM
- Shrinkage
- Quality
- Defect rate
- Color consistency
- MOQ
- Lead time
The meaningful comparison is between fabrics that actually meet the same requirements.
How to Find Fabric Suppliers for Your Clothing Brand
Brands can browse textile companies on TurkishTextile.org to discover fabric manufacturers and suppliers.
When contacting suppliers, provide a clear requirement instead of asking for a complete catalogue without explaining what you need.
For example:
Looking for Fabric for an Oversized T-Shirt Collection
We are looking for 100% cotton single jersey fabric for an oversized T-shirt collection. Required weight: approximately 220 GSM. Minimum usable width: 180 cm. Initial colors: black, white and navy. Initial requirement: approximately 500 kg per color. Please provide MOQ, available stock colors, production lead time, sample availability and quotation.
If you cannot find the required fabric, you can publish a textile buying request so suppliers can review your specifications.
For ready-made inventory, brands can also browse textile classifieds.
Before Ordering Fabric for Your Brand
Before approving fabric for a clothing collection, confirm:
Is the composition correct?
Is the construction suitable for the garment?
Is the GSM appropriate?
Is the usable width acceptable?
Does the fabric have the required stretch and hand feel?
Has a sample garment been produced?
Has wash performance been evaluated where necessary?
Can the supplier meet the required MOQ?
Can the fabric be supplied again?
Can the supplier maintain consistent quality and color?
Fabric sourcing should begin with the garment you want to create.
The objective is not simply to find attractive fabric.
It is to find a fabric that can be produced, sewn, worn and reordered in a way that supports the product and the clothing brand behind it.
