Flappers were a subculture of young Western women prominent after the First World War and through the 1920s who wore short skirts (knee height was considered short during that period), bobbed their hair, listened to jazz, and flaunted their disdain for prevailing codes of decent behavior. Flappers were seen as brash for wearing excessive makeup, drinking alcohol, smoking cigarettes in public, driving automobiles, treating sex in a casual manner, and otherwise flouting social and sexual norms.[1] As automobiles became more available, flappers gained freedom of movement and privacy.
