Silk faille fabric features a distinctive ribbed texture, a subdued yet elegant sheen and a heavy weight. The characteristic corded effect in silk faille is produced by including, at regular intervals in the weave, a thicker yarn, leaving soft, wide, strongly defined ribs. Faille is a plain weave textile and is finer than grosgrain, a well-regarded sturdy woven corded fabric.
Silk faille has a smooth, lustrous feel and easy drape. These, combined with a readiness to take a crease, make silk faille popular for elegant apparel that's pleated or tailored. Silk faille fabric is widely used in dresses, skirts and slacks, as well as in tasteful home décor applications, and, in heavier weights, the material works well in coats and suits.

In addition to stocking faille in a variety of colors, many fabric supply stores carry undyed or white fabric which you can dye to your own specifications. Since ribbed fabrics can be challenging to dye at times, it is a good idea to consult someone who is experienced with textiles about dyeing faille, to ensure that you get a smooth, even look.
