Leggings fabrics need controlled four-way stretch, recovery, opacity and a stable surface for repeated movement.
Define target compression level and opacity expectation.
Specify four-way stretch and any elongation/recovery test target.
Confirm GSM, finished width, hand, shade and pilling/fastness requirements.
For leggings, start with the densest four-way stretch options and validate opacity and recovery on the intended garment pattern.
Ranking is deterministic and uses only current catalogue data: exact end-use tags, construction, stretch, GSM fit, family and listed properties. It is a sourcing shortlist, not a claim that one fabric is universally best.
Send the garment, GSM, width, stretch, finish, volume and testing requirements.
