How to prepare a fabric sourcing brief: a practical guide for clothing brands.

Finding the right fabric begins with asking the right questions. Whether you are developing your first clothing collection, sourcing materials for an established garment business or looking for an alternative to an existing fabric, the quality of your sourcing brief can make a significant difference.

An incomplete enquiry may lead to unsuitable samples, repeated clarification, inaccurate quotations or unexpected minimum order quantities. A well-prepared brief helps reduce these uncertainties.

It does not need to be complicated. It simply needs to communicate what you are making, what matters most and which requirements are flexible. Here are the key details worth preparing before approaching a fabric supplier or sourcing partner.

1Start with the intended product

Before specifying the material, explain what you plan to make. A fabric intended for a formal business shirt will have different requirements from one intended for a polo shirt, casual T-shirt, uniform or tailored garment. The intended product provides context for decisions about construction, weight, comfort and finishing.

Useful information includes:

• Garment type and intended use
• Target customer or market
• Desired appearance and feel
• Expected wearing conditions
• Any particular performance requirements

For example, a men's polo shirt designed for everyday use in the UAE may require a balance of breathability, softness, structure and shape retention. Communicating this objective is more useful than requesting a fabric based on appearance alone.

2Specify the fibre composition

Fibre composition is one of the most important elements of a sourcing brief. Examples include:

• 100% cotton
• Cotton and polyester blends
• Cotton with elastane
• Linen and cotton blends
• Wool or wool blends

If you have a preference for a particular cotton type, yarn preparation or finishing process, include it. You may be interested in Pima cotton, combed compact cotton yarn or mercerised cotton, for example. These terms describe different characteristics or processing methods and should not be treated as interchangeable.

It also helps to distinguish between essential and preferred requirements. If 100% cotton is mandatory, state that clearly. If you are open to a suitable blend, let the supplier know. This allows alternatives to be considered without compromising the requirements that matter most.

3Identify the fabric construction

The construction of a fabric affects its texture, appearance, flexibility and potential applications. For woven fabrics, common options include poplin, twill and Oxford. For knitted fabrics, options may include single jersey, interlock, rib and piqué.

If you know the construction you require, specify it. If you are uncertain, describe the intended appearance and feel, and provide a reference image or sample. A clear description might be:

Fine cotton piqué with a subtle texture, soft hand feel and enough structure to maintain a neat polo-shirt silhouette.

This communicates more than simply requesting high-quality cotton fabric.

4Define the target fabric weight

Fabric weight is commonly expressed in grams per square metre, or GSM. Including a target GSM helps suppliers narrow down suitable materials, for example:

Target weight: 190–220 GSM.

If the weight is flexible, explain the reason for the range. You might prioritise softness and breathability over a specific number, or require enough structure for a particular garment.

Avoid specifying GSM without considering construction and intended use: a woven fabric and a knitted fabric with identical GSM values may behave very differently. Read more about GSM.

5Clarify colour and finishing requirements

Colour can have a significant effect on sourcing availability, minimum order quantities and lead times. Specify whether you require:

• Available stock colours
• Custom-dyed colours
• A physical colour reference
• A recognised colour standard
• Multiple colours within the same order

For custom colours, a physical reference or clearly identified standard can help communicate the target shade. However, colour appearance can vary across materials and viewing conditions, so physical lab dips or approved colour samples may be needed before production.

Finishing requirements should also be communicated. Depending on the fabric, these might include a softening treatment, mercerisation, pre-shrinking or other specified processes. Only request treatments that serve a genuine product requirement.

6Consider fabric width and usable yield

Fabric width is sometimes overlooked during initial sourcing discussions, yet it can directly affect cutting efficiency, material consumption and production cost.

For woven fabrics, width is often stated in centimetres or inches. Knitted fabrics may be supplied in open-width or tubular form, depending on their construction and the supplier's production arrangements.

When comparing quotations, confirm whether the stated width refers to total width or usable width. A lower price per metre may not represent better value if the usable width is substantially narrower. Garment manufacturers can help determine the width best suited to their cutting and production requirements.

7Provide realistic quantities

Suppliers need to understand how much fabric you intend to purchase. Where possible, provide:

• Estimated total quantity
• Quantity per colour
• Preferred unit, such as metres or kilograms
• Whether the order is for sampling, initial production or repeat supply

Minimum order quantities can vary significantly depending on the fabric, colour, finishing and whether material is available from stock. For an emerging clothing brand, it may be useful to ask about available stock fabrics before considering custom production. Stock options can offer greater flexibility, although availability and consistency across future orders should be considered.

8Define quality and performance expectations

Terms such as premium quality, excellent fabric or export quality are subjective. They do not provide a measurable basis for evaluation. Where performance matters, identify the relevant requirements. These may include:

• Dimensional stability after washing
• Colourfastness
• Pilling resistance
• Fabric strength
• Surface appearance
• Acceptable variation in weight or width

For important requirements, specify the applicable test method and acceptance criteria where known. Testing and certification should be discussed separately from visual or tactile sample approval: a fabric that feels suitable during sampling may still require further evaluation before bulk production.

9Explain your timeline and delivery requirements

A sourcing enquiry should include your intended purchasing timeline. It helps to distinguish between:

• When you need initial fabric options
• When samples are required
• When the bulk order may be confirmed
• When the fabric needs to arrive

Delivery destination also matters. For international orders, freight arrangements, customs requirements and agreed trade terms can influence the overall cost and timeline. Providing these details early helps suppliers judge whether a proposed material is commercially practical.

10Include reference materials

You do not need a complete technical specification to begin a sourcing conversation. An existing fabric swatch, garment sample or clear photograph can provide a useful reference.

However, photographs cannot reliably establish exact composition, GSM, texture or performance. A physical sample is often more informative, particularly when matching an existing fabric. Where exact replication is important, further technical assessment may be necessary.

Example: a simple fabric sourcing brief

The following example illustrates how the information can be organised for an initial enquiry.

This is an illustrative sourcing brief, not a quotation or confirmation of fabric availability.

A brief like this provides enough information to begin a meaningful discussion while allowing the supplier to suggest alternatives where appropriate.

What if you don't know all the specifications?

That is entirely normal, particularly for businesses developing new products. You may know how you want the fabric to feel without knowing its yarn count or construction. You may have a reference garment but no information about its material. Or you may understand the product requirements but need help comparing available fabric options.

The important thing is to distinguish what you know, what you prefer and what still needs to be determined. A good sourcing conversation should help clarify those details rather than assume that every customer arrives with a complete technical specification.

A better starting point

Fabric sourcing is ultimately about matching a material to its intended purpose. A clear brief makes that process more efficient, and it also encourages better decisions: it allows businesses to compare options on a consistent basis, evaluate commercial trade-offs and reduce misunderstandings before committing to an order.

The objective is not simply to find a fabric that meets a description. It is to find a material that makes sense for the product, the customer and the business behind it.
