Jeans are trousers often made from denim or dungaree cloth. Often the term "jeans" refers to a particular style of pants, called "blue jeans" and invented by Jacob Davis and Levi Strauss in 1873. Starting in the 1950s, jeans, originally designed for cowboys and miners, became popular among teenagers, especially members of the greaser subculture. Historic brands include Levi's, Lee, and Wrangler. Jeans come in various fits, including skinny, tapered, slim, straight, boot cut, narrow bottom, low waist, anti-fit, and flare.
