A skinhead or skin is a member of a subculture that originated among working-class youth in London, England, in the 1960s. It soon spread to other parts of the United Kingdom, with a second working-class skinhead movement emerging worldwide in the late 1970s. Motivated by social alienation and working-class solidarity, skinheads are defined by their close-cropped or shaven heads and working-class clothing such as Dr. Martens and steel toe work boots, braces, high rise and varying length straight-leg jeans, and button-down collar shirts, usually slim fitting in check or plain. The movement reached a peak at the end of the 1960s, experienced a revival in the 1980s, and, since then, has endured in multiple contexts worldwide.
