Street style has evolved from a common social practice adopted by particular sociocultural groups to an important segment of mass fashion industry. This process was very long; it was accompanied by extensive social, cultural and economic changes. The chaos that occurred after World War II had an impact on the overall growth of mass culture. It was a period when people wanted to make a change from the already-known ordinary style. As a result, various groups occurred, each with its own different style: hippies, punks, goths or bikers.
