Chiffon, 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.[1] 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 most commonly used in evening wear, especially as an overlay, giving an elegant and floating appearance to the gown. It is also a popular fabric used in blouses, ribbons, scarves and lingerie. Like other crepe fabrics, chiffon can be difficult to work with because of its light and slippery textures. Due to this delicate nature, chiffon must be hand washed very gently.[1]
Since chiffon is a light weight fabric that frays very easily, bound or French seams must be used to stop the fabric from fraying.
