Chiffon, from the French word chiffe which means "cloth or rag"; is a lightweight, balanced plain-woven sheer fabric, or gauze, like gossamer, woven of alternate S- and Z-twist crepe (high-twist) yarns. Crepe yarn tends to have a tighter twist than standard yarns. The twist in the crepe yarns puckers the fabric slightly in both directions after weaving, giving it some stretch and a slightly rough feel.
