Spandex / Elastane
“Powerful stretch and recovery, even in small amounts”
Spandex is usually blended in at low percentages to help clothing move with you and spring back into shape. The fabric's construction determines how far—and in which directions—it stretches.
Like the snug stretch and bounce-back of leggings
Fiber percentages alone cannot tell whether the fabric will look shiny or matte. Yarn shape and finishing can make a substantial difference.
The surface may range from smooth to softly brushed, so actual product photos will be especially helpful.
Whether the fabric flows or holds its shape depends heavily on its construction and weight.
