Flappers were the younger generation of Western women in the 1920s who wore skirts, wore flowing hair, listened to jazz music, and showed disdain for behavior that was then deemed acceptable. Flatterers are considered criminals for wearing excessive makeup, drinking alcohol, smoking cigarettes in public, driving cars, treating sex normally, and otherwise violating social and sexual norms. As cars become available, flappers gain freedom of movement and privacy. Flappers are a symbol of the Roaring Twenties, the social and political turmoil and increase in transatlantic cultural exchange after the end of World War I, as well as the export of American jazz culture to Europe. There is a reaction to this counterculture from more conservative people, who are mostly of the older generation. They claimed that the skirts of the flappers were 'almost nude', and the flappers were 'casual', 'reckless' and unintelligent.
