Faille is a type of ribbed fabric traditionally made from silk, although it may contain cotton, cotton blends, wool or manufactured fibers, such as rayon. It was used extensively for formal wear during the 1940s and 1950s.
Because it comes in a variety of weights, faille is used to construct many types of clothing, including suits, evening wear, coats, skirts and wedding gowns. Heavier grades of the fabric are also found in home decor. Faille is also often used to create fabric with a "moire," or wood grain, design. Although faille has a slight stiffness, it drapes very well and resists wrinkling, staining and tearing. Because of the ribbing in faille, care must be taken when putting together projects, or undesirable patterns of lines may appear.
