Taffeta
Taffeta is a crisp, smooth, plain woven fabric made from silk, nylon, cuprammonium rayons, acetate, or polyester. The word came into Middle English via Old French and Old Italian, which borrowed the Persian word tāfta (تافته), which means "silk" or "linen cloth". As clothing, it is used in ball gowns, wedding dresses, and corsets, and in interior decoration, for curtains or wallcovering. It tends to yield a stiff cloth with a starched appearance that holds its shape better than many other fabrics and does not sag or drape.
