. . . "Jeans are trousers typically made from denim or dungaree cloth. Often the term \"jeans\" refers to a particular style of pants, called \"blue jeans,\" which were invented by Jacob Davis in 1871 and patented by Davis and Levi Strauss on May 20, 1873. Originally designed for cowboys and miners, jeans became popular in the 1950s among teenagers, especially members of the greaser subculture."@en .
