Gown material is an important part of any formal dress. ORGANZA, SATIN, TULLE, and TAFFETA are all popular materials used to make gowns. ORGANZA is a sheer, lightweight fabric made from silk or synthetic fibers. SATIN is a smooth, glossy fabric with a lustrous sheen. TULLE is a fine, lightweight netting fabric often used for veils and skirts. TAFFETA is a crisp, smooth fabric with a slight sheen. All of these fabrics can be used to create beautiful gowns for special occasions.
