Choose material by performance, hand, drape, surface, decoration compatibility and care—not by a weight number alone.
Weight helps describe a fabric, but knit construction, fiber, finishing and density decide how the garment actually behaves. Approve the physical swatch and sample.
Loopback, brushed, compact, slub, ribbed, twill and canvas surfaces change both the visual result and decoration response.
Garment wash, pigment direction, distressing and other treatments can affect shade, hand and measurement. Sample on the final construction where possible.
Build a color standard from an approved physical reference and document how it will be evaluated. Screen color alone is not a production standard.
