Fabric Sourcing for Fashion Brands: How to Choose the Right Material and Supplier

Fabric Sourcing for Fashion Brands: How to Choose the Right Material and Supplier The fabric is not just one line in a bill of materials. It determines how a garment looks, feels, fits, performs, washes, and ages. A strong design made in the wrong material can become uncomfortable, difficult to sew, or too expensive to produce. The right fabric can make a simple product feel distinctive and valuable. For a new fashion brand, sourcing fabric can be one of the most confusing parts of product development. Suppliers use technical terms, minimum quantities vary, colours can change between production lots, and a beautiful swatch may behave differently after cutting, sewing, washing, or wearing. This guide explains how to define your fabric requirements, compare suppliers, test materials, manage minimums, and document the final choice for production. Start with the product—not the supplier catalogue Before searching for fabric, define what the garment needs to do. A supplier can recommend better options when the request is connected to a clear product. Consider: • Garment type and intended use • Target customer and climate • Required drape, structure, stretch, or recovery • Desired softness, texture, weight, and opacity • Fit and construction method • Colour and finish • Care requirements • Performance needs such as moisture management, abrasion resistance, or water repellency • Target price and order quantity • Brand requirements for fibre origin, recycled content, or certifications A lightweight woven that works beautifully for a relaxed blouse may be unsuitable for a structured overshirt. A soft jersey may feel premium but stretch too much for the planned neckline. Define the performance first, then evaluate the visual qualities. Understand the key fabric specifications Fabric names alone are not precise enough. Two suppliers may both offer “cotton jersey,” but the materials can have very different weights, constructions, finishes, and shrinkage. Record the following information whenever possible: Fibre content Fibre content describes the material composition, such as cotton, polyester, viscose, wool, nylon, linen, elastane, or a blend. The percentages affect comfort, durability, stretch, care, cost, and labelling. Fabric construction Construction explains how the yarns are made into fabric. Woven materials include plain weave, twill, satin, poplin, canvas, and many other structures. Knitted materials include single jersey, rib, interlock, pique, fleece, and more. Weight Fabric weight is often expressed in grams per square metre, or GSM. A higher GSM usually means more material per square metre, but it does not automatically mean better quality. Construction, fibre, yarn, and finish also affect the result. Width Usable fabric width influences consumption and marker efficiency. Confirm whether the quoted width includes or excludes the selvedge. Stretch and recovery For stretch garments, document the percentage of stretch in each direction and how well the fabric returns to its original dimensions. Poor recovery can lead to bagging at knees, elbows, waistbands, or necklines. Finish Brushing, peaching, mercerising, coating, washing, compacting, calendaring, anti-pilling treatment, and other finishes can change the surface, performance, shrinkage, and cost. Colour information Record whether the fabric is stock-dyed, yarn-dyed, piece-dyed, garment-dyed, or printed. Confirm the colour standard, dye-lot rules, minimum quantity, and approval process. Create a fabric specification sheet Turn the design intent into a short material brief. Include a reference code, fibre content, construction, weight, width, colour, finish, stretch, performance requirements, testing requirements, approved supplier, price, minimum quantity, and lead time. Add the final fabric to the garment’s bill of materials and tech pack. This gives the factory a clear source of truth and reduces the risk of an unapproved substitute. ThreadPack helps designers organise fabric specifications, trims, colourways, construction details, measurements, and revision notes in one factory-ready product document. Where fashion brands source fabric Fabric mills Mills manufacture fabric and may offer custom construction, colour, finish, or printing. They can be suitable for larger orders or brands that need a specific material developed. Customisation usually comes with higher minimum quantities and longer lead times. Converters Converters buy unfinished or base fabric and arrange dyeing, printing, coating, or finishing. They can provide specialised effects without owning every stage of production. Agents and sourcing companies Agents connect brands with mills and may help with communication, quality control, logistics, and smaller orders. Understand how the agent is paid and which responsibilities are included. Wholesalers and jobbers Wholesalers carry ready-made fabrics, sometimes in relatively small quantities. Jobbers may sell limited surplus, cancelled, or deadstock materials. These sources can be useful for small collections, but repeat availability may be uncertain. Your garment manufacturer Full-package manufacturers often source fabrics through an established supplier network. This can simplify development and production, but the brand should still approve the exact fabric, price, test results, colour, and source. Trade shows and online marketplaces Trade shows allow designers to compare many suppliers and handle materials in person. Online platforms can expand access, but samples, supplier verification, and written specifications remain essential. Request swatches before sample yardage Begin with a focused swatch request rather than ordering many unrelated materials. Send the supplier your product brief and ask for options that meet the key requirements. When reviewing a swatch: • Check colour in natural and controlled light • Feel both sides of the fabric • Hold it against the body or a dress form • Observe drape, bounce, opacity, and surface texture • Stretch it in each direction and check recovery • Rub the surface to look for shedding or early pilling • Fold and crease it • Compare it with your target retail price and quality position Keep every swatch labelled with the supplier, article number, composition, weight, width, colour, date, and quoted price. An unlabelled fabric becomes difficult to trace later. Order sample yardage and make a garment A small swatch cannot show how the material will behave across a complete garment. Before bulk production, order sample yardage and use it for development. The sample-making process may reveal that the fabric: • Slips or stretches during cutting • Requires a different needle, thread, stitch, or seam • Shrinks or twists after washing • Becomes transparent under tension • Feels heavier than expected in the full garment • Does not hold the planned shape • Produces excessive lint or surface damage • Changes colour after pressing or wet processing Fit should be approved in the intended fabric whenever possible. Replacing the material after fit approval can change the garment’s measurements, drape, and balance. Test the fabric for its real use Testing should reflect the product, market, care instructions, and risk level. Depending on the garment, useful checks may include: • Dimensional stability and shrinkage • Colourfastness to washing, rubbing, perspiration, or light • Pilling and abrasion resistance • Stretch and recovery • Seam slippage or seam strength • Fabric strength and tearing • Spirality or skew • Print or coating durability • Fibre-content verification • Restricted-substance or product-safety requirements Home wash tests can provide early development feedback, but they may not replace accredited laboratory testing when formal results are required. Agree with the supplier and factory on the applicable standards, test method, passing criteria, responsibility, and timing. Understand MOQ, MCQ, and minimum dye quantities MOQ is the minimum order quantity a supplier will accept. MCQ is a minimum colour quantity. A mill may accept a total order across several colours but require a minimum amount in each colour. Ask: • Is the minimum measured in metres, yards, kilograms, rolls, or another unit? • Does the MOQ apply per construction, colour, print, or finish? • Is there a surcharge for lower quantities? • Can colours be combined? • Is the material made to order or available from stock? • What quantity variation is allowed between ordered and delivered amounts? For a small brand, stock service fabric can reduce risk. A custom fabric may create stronger differentiation, but it also requires more cash, development time, and inventory commitment. Calculate the real fabric cost Do not compare suppliers only by price per metre. The final garment cost is affected by usable width, shrinkage, defects, fabric weight, cutting waste, minimums, freight, duty, testing, and excess material. Ask the factory to calculate consumption using the final pattern and realistic marker efficiency. A fabric with a higher price per metre can sometimes produce a similar garment cost if it is wider, more stable, or easier to cut efficiently. Also confirm the quotation currency, validity period, payment terms, Incoterm, packing method, and whether tax or freight is included. Evaluate the supplier, not only the fabric A beautiful material is not enough if the supplier cannot deliver consistent bulk production. Evaluate: • Experience with your product category • Communication speed and accuracy • Ability to provide complete specifications • Sample and bulk lead times • Colour-matching process • Quality-control procedures • Traceability and certification evidence • Capacity and repeat availability • Claims process for defects or shortages • Willingness to confirm decisions in writing Ask for the legal business name, address, references, relevant documents, and sample test reports where appropriate. If responsible sourcing is part of your brand promise, verify claims rather than relying on marketing language alone. Approve colour and bulk fabric carefully For custom-dyed fabric, the supplier may submit lab dips—small colour samples prepared for approval. Review them against the correct colour standard under agreed lighting conditions. Before cutting, approve bulk fabric or a production cutting. Confirm colour, hand feel, finish, weight, width, shrinkage, and appearance. Dye lots can vary, so the factory should shade-sort rolls and avoid mixing visibly different shades within one garment. Create a signed and dated approval record. Verbal approval is difficult to trace when a problem appears later. Plan lead time and continuity Fabric often controls the production schedule. Ask separately about yarn or greige availability, dyeing, finishing, testing, transport to the factory, and potential delays around holidays or peak periods. For repeat styles, discuss whether the supplier can reserve base material, maintain a stock programme, or reproduce the same construction and colour in future seasons. Keep a retained swatch from approved bulk production as the reference for future orders. Fabric sourcing red flags Be cautious when a supplier: • Cannot provide a clear specification • Changes composition, weight, width, or price without explanation • Refuses to send labelled samples • Promises custom colours with no approval process • Avoids questions about testing or traceability • Cannot explain MOQ and lead time • Pressures you to pay before issuing a complete quotation • Sends bulk material that differs from the approved sample Small differences can occur in textiles, but expectations and tolerances should be discussed before production. Final fabric-sourcing checklist Before approving a material, confirm that: • The fabric matches the garment’s function and target customer • Composition, construction, weight, width, finish, and colour are documented • Sample yardage has been cut and sewn into the product • Fit and care performance are acceptable • Required tests and passing standards are agreed • MOQ, colour minimum, lead time, and price are confirmed • Consumption and landed cost support the target margin • The supplier and relevant claims have been verified • Bulk approval and shade-control procedures are defined • The approved fabric is recorded in the BOM and tech pack The best fabric is not simply the softest, newest, or cheapest option. It is the material that delivers the intended design, performs reliably, fits the cost target, and can be supplied consistently. Build a clear specification, test before bulk, document every approval, and treat the supplier as a long-term production partner.
