Fabric selection is one of the most consequential decisions in a T-shirt or hoodie program. Weight alone does not define quality. Two fabrics with the same grams per square meter can behave differently because of yarn, knit structure, finishing, stretch and compactness.
Start with the intended wearer and product behavior, then translate those needs into material properties a supplier can source and sample.
Define the product before the fabric
Describe whether the garment should feel crisp or fluid, light or substantial, smooth or textured, fitted or oversized. Consider climate, layering, decoration and expected care. A heavy fabric may support a structured silhouette but feel unsuitable for warm-weather use; a soft, drapey jersey may not hold an oversized shape in the same way.
Understand common knit structures
| Structure | Typical characteristics | Useful applications |
|---|---|---|
| Single jersey | Flexible face, lighter construction, natural curl at cut edges | T-shirts and lightweight tops |
| Interlock | Smooth on both sides, stable and relatively dense | Premium tees and fitted styles |
| French terry | Smooth face with looped back | Sweatshirts, shorts and transitional layers |
| Brushed fleece | Soft brushed interior with warmth and volume | Hoodies and cold-weather sweats |
| Rib knit | High stretch and recovery when correctly specified | Neckbands, cuffs and fitted garments |
Evaluate more than composition
- Fabric weight and actual tolerance
- Yarn count and surface appearance
- Stretch percentage and recovery
- Width and usable cutting width
- Shrinkage after the intended wash
- Pilling and abrasion expectations
- Colorfastness appropriate to the end use
Match fabric to decoration
Printing, embroidery and wash treatments place different demands on fabric. A highly textured or unstable surface can reduce print definition. Dense embroidery may distort lightweight knits without suitable backing. Garment washes can change shade, hand feel and dimensions, so decoration and finishing should be evaluated on the actual fabric rather than separately.
Use swatches and garment samples together
A hand swatch helps compare surface and color, but it cannot show how the material behaves in a hood, waistband or oversized body. Approve the fabric in a representative garment sample whenever drape, recovery or shrinkage influences the fit.
Browse the custom apparel product range to identify the silhouette and construction category you want to develop before requesting material options.
Fabric questions for an RFQ
- What property or reference defines the desired hand feel?
- Is the listed weight nominal or measured after finishing?
- What shrinkage should be used for pattern planning?
- Will rib and body fabric be dyed to match?
- Has decoration been tested on the intended material?
- Is continuity required for future repeat orders?
Create a fabric evaluation scorecard
Compare candidate fabrics against the intended garment rather than judging swatches in isolation. Create a simple scorecard for silhouette, hand feel, weight, stretch, recovery, opacity, surface, warmth, decoration compatibility and care. Weight the factors that matter most to the target customer instead of treating every property equally.
Ask for measured information with each swatch. Composition and nominal weight are useful, but fabric width, usable width, shrinkage, stretch direction and finishing method affect pattern planning and cost. Record the supplier article or internal reference so the approved swatch can be traced when bulk material is ordered.
Make representative samples in the strongest candidates. Wash or finish them using the intended process, then compare dimensions, twist, surface, shade and hand feel. A fabric that feels excellent before washing may lose the structure or recovery needed for a neckline, cuff or oversized body.
Evaluate body fabric and rib together. Neckbands and cuffs need compatible stretch, recovery, thickness and shade. A rib that is too soft can produce a loose opening, while a heavy rib can distort a lighter body. Approve the combination in a garment, not as two separate swatches.
Include decoration in the material trial. Print a representative area, embroider the expected density and apply the planned wash or heat process. Review the face and inside of the garment for distortion, stiffness, show-through or discomfort. These checks are especially important when artwork coverage is large.
Once the fabric is selected, document the properties that must remain consistent in bulk. If an exact article cannot be guaranteed for repeat orders, identify which changes require a new sample. This creates a useful boundary between an acceptable equivalent and a material that changes the product.
Questions to ask before you proceed
- Which property creates the intended silhouette?
- What changes after washing or finishing?
- How will body and rib shades be controlled?
- Is the surface suitable for the decoration method?
- Which measured properties define an acceptable equivalent?
- Can the material be repeated for future orders?
