Crepe is a weaving or fabric treatment method that results in a unique rippling, three-dimensional texture. Garments and other textiles made with crepe fabric are generally delicate and used for ceremonial occasions.

Traditionally, crepe fabric was worn by women at times of mourning in many Western cultures, but this practice has largely gone out of fashion. Other cultures around the world incorporate various types of crepe fabric into their textile manufacturing, and in some cases, traditional crepe fabric is still used that has been woven the same way for thousands of years.
