Chiffon, French pronunciation: [ʃi.fɔ̃], from the French word for a cloth or rag, is a lightweight, balanced plain-woven sheer fabric woven of alternate S- and Z-twist crepe (high-twist) 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.

Chiffon is made from cotton, silk or synthetic fibres. Chiffon can be dyed to almost any shade, but chiffon made from polyester can be difficult to dye. Under a magnifying glass it resembles a fine net or mesh which gives chiffon some see-through properties.

Chiffon is most commonly used in evening wear, especially as an overlay, for giving an elegant and floating appearance to the gown. It is also a popular fabric used in blouses, ribbons, scarves and lingerie. Like other crêpe fabrics, chiffon can be difficult to work with because of its light and slippery texture. Due to this delicate nature, chiffon must be hand washed very gently.

Since chiffon is a light-weight fabric that frays very easily, bound or French seams must be used to stop the fabric from fraying. Chiffon is smoother and more lustrous than the similar fabric georgette.
