Chiffon is a lightweight, balanced plain-woven sheer fabric woven of alternate S- and Z-twist crepe (high-twist) yarns.
Early chiffon was made purely from silk. In 1938, however, a nylon version of chiffon was invented, and in 1958 polyester chiffon was invented and became immensely popular due to its resilience and low cost. Under a magnifying glass chiffon resembles a fine net or mesh, which gives it some transparency.
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.
