Understanding the Difference Between Denim and Jeans

Denim is a strong cotton fabric made using a [twill weave](https://www.masterclass.com/articles/what-is-twill-fabric-definition-and-characteristics-of-the-popular-twill-weave), which creates a subtle diagonal ribbing pattern. First produced as *serge de Nîmes* in France in the seventeenth century, the cotton twill fabric is warp-facing, meaning that the weft threads go under two or more warp threads. The warp yarns are more prominent on the right side—these diagonal parallel lines make denim fabric different from other sturdy woven cotton fabrics like canvas or cotton duck.
