Chiffon: Delicate, sheer, and transparent -- made from silk or rayon, with a soft finish; often layered because of its transparency, making it popular for overskirts, sheer sleeves, and wraps. Organza: Crisp and sheer like chiffon, with a stiffer texture similar in effect to tulle, but more flowing; popular for skirts, sleeves, backs, and overlays.

Satin: A heavy, smooth fabric with a high sheen on one side; very common in bridal gowns.

Silk: The most sought-after, cherished fiber for wedding dresses (and also the most expensive).

Silk-Like Satin: A smooth silk satin, with a glossy front and matte back.

Taffeta: Crisp and smooth, with a slight rib.

Tulle: Netting made of silk, nylon, or rayon; used primarily for skirts and veils (think ballerina tutus).
