The Three Pillars of Fabric Selection
When sourcing fabric for a garment line, three characteristics determine whether a material will work: weight (gsm), drape (how it hangs), and hand-feel (how it feels to touch). Understanding these helps you avoid costly sampling mistakes and ensures your finished garment matches the designer’s vision.
Fabric Weight: GSM Explained
Fabric weight is measured in grams per square meter (gsm). It directly affects the garment’s structure, warmth, and suitability for different end-uses.
| Category | GSM Range | Typical Use |
|---|---|---|
| Ultra-light | 30–80 gsm | Lining for lightweight dresses, blouses |
| Light | 80–130 gsm | Standard suit lining, shirting |
| Medium | 130–200 gsm | Jacket lining, lightweight outerwear |
| Heavy | 200–350 gsm | Overcoat lining, performance outerwear |
| Ultra-heavy | 350+ gsm | Workwear, heavy-duty outerwear |
Key rule: Lighter linings drape more fluidly but offer less structure. Heavier linings provide shape and warmth but can overwhelm lightweight shell fabrics.
Drape: The Art of How Fabric Falls
Drape refers to how fabric hangs under its own weight. It is influenced by fiber type, yarn twist, weave structure, and finishing.
High-Drape Fabrics
- Viscose & rayon — fluid, silk-like fall; ideal for dresses and formal linings
- Silk & silk blends — natural liquid drape; premium womenswear
- Tencel / Lyocell — eco-friendly alternative with excellent drape
Medium-Drape Fabrics
- Polyester crepe — balanced drape with body; versatile for suits and separates
- Viscose-polyester blends — practical drape with added durability
Low-Drape (Structured) Fabrics
- Nylon taffeta — crisp, rustling drape; ideal for puffer jackets and down-proof linings
- Cotton canvas — stiff, holds shape; workwear and structured garments
Hand-Feel: What Your Customer Touches
Hand-feel (or “handle”) is the tactile sensation of fabric. It is often the make-or-break factor in a customer’s purchase decision. Key descriptors:
- Soft / Smooth — desirable for linings that touch skin (viscose, cupro, Supplex)
- Crisp / Rustling — associated with quality in formalwear linings (taffeta)
- Dry / Matte — preferred for technical outerwear (brushed polyester)
- Slick / Slippery — functional for easy on/off (satin-weave linings)
Matching Fabric to Garment: A Quick Reference

| Overcoat lining | 120–180 gsm | Medium | Viscose-Poly blend |
| Puffer jacket lining | 50–80 gsm | Low | Nylon taffeta |
| Dress lining | 60–100 gsm | High | Silk, Viscose |
| Activewear lining | 70–110 gsm | Medium | Polyester mesh, Supplex |
