The Custom Apparel Glossary: 40 Terms Every Brand Should Know

By The Velocity Wear Team

Ordering custom apparel means meeting a wall of jargon — GSM, DTF, MOQ, DDP, tech packs and more. Here is a plain-English glossary of the terms you will actually come across, grouped so you can find them fast.

Fabric & garment terms

  • GSM — grams per square metre; the weight and density of a fabric, and the best single quality indicator.
  • Combed cotton — cotton with short fibres removed for a smoother, stronger, softer yarn.
  • Ring-spun — yarn spun by twisting fibres into a finer, softer, stronger strand.
  • Staple length — fibre length; longer staples make better cotton (e.g. Pima).
  • Piqué — a textured knit used for polo shirts; breathable and structured.
  • Fleece — the brushed or looped knit used for hoodies and sweats (loopback or brushed-back).
  • Pre-shrunk — fabric treated so it will not shrink significantly after washing.
  • Colourfast — dyed so the colour resists fading and bleeding in the wash.
  • Grading — how measurements step up from one size to the next across a size run.
  • GSM vs oz — denim and some fabrics are measured in ounces per square yard instead of GSM.

Printing & decoration

  • DTF — direct-to-film; full-colour transfer printing with no per-design minimum.
  • Screen printing — ink pushed through a stencil, one screen per colour; durable at volume.
  • Plastisol — a plastic-based screen ink that is opaque and very durable.
  • Water-based ink — a screen ink that soaks into the fabric for a soft, vintage finish.
  • Discharge — removing garment dye and replacing it with new colour for a soft result on darks.
  • Sublimation — dye baked into polyester for all-over, crack-proof prints.
  • Embroidery — a design stitched into the fabric with thread.
  • Digitizing — converting a logo into a machine stitch file for embroidery.
  • 3D puff — raised embroidery, popular on caps.
  • Vector — scalable artwork (AI, EPS, PDF) that stays sharp at any size.
  • Pantone — the standard physical colour-matching system (TCX/TPX for fabric, C/U for ink).

Production & business

  • MOQ — minimum order quantity; the fewest units a manufacturer will produce per design.
  • Blank — an undecorated garment before printing or embroidery.
  • Tech pack — the technical blueprint of a garment used for manufacturing.
  • BOM — bill of materials; every fabric, trim and component in a garment.
  • Sample / strike-off — a pre-production proof of the garment or print, for approval.
  • Sew-out — a stitched proof of an embroidery design.
  • Cut-and-sew — making a garment from scratch from fabric, not decorating a blank.
  • Private label — selling quality blanks under your own brand with custom labels.
  • Lead time — the total time from approval to delivery.
  • Incoterms — who pays for shipping, duties and taxes (e.g. DDP, FOB, EXW).
  • DDP — delivered duty paid; an all-in landed price including shipping and duties.
  • AOV — average order value; the average a customer spends per order.

FAQ

Quick Answers

Common questions about ecommerce — answered.

GSM is grams per square metre — the weight and density of a fabric. Higher GSM generally means a heavier, more substantial, more premium garment, making it the best single indicator of quality.

DTF is full-colour transfer printing with no minimum; screen printing pushes ink through a stencil and is durable and cost-effective at volume; embroidery stitches the design into the fabric for a premium, durable finish. Each suits different designs and quantities.
