Denim is a rugged cotton twill textile, in which the weft passes under two or more warp fibers. This produces the familiar diagonal ribbing identifiable on the reverse of the fabric, which distinguishes denim from cotton duck. Denim has been in American usage since the late eighteenth century. The word comes from the name of a sturdy fabric called serge, originally made in N?mes, France, by the Andre family. Originally called serge de N?mes, the name was soon shortened to denim. Denim was traditionally colored blue with indigo dye to make blue "jeans," though "jean" then denoted a different, lighter cotton textile; the contemporary use of jean comes from the French word for Genoa, Italy , where the first denim trousers were made.
