The flapper was a young, fashionable woman in the 1920s who rejected conventional behavior and pushed gender boundaries. They wore short skirts and dresses, used flapper slang like "jazz" and were influenced by designers like Coco Chanel who popularized simple, loose dresses allowing freedom of movement. Flappers represented sexual and economic freedom through their lifestyle which included public partying, drinking, dancing and more liberal attitudes towards relationships and sexuality. However, the flapper lifestyle declined after the 1929 stock market crash and Great Depression as their carefree attitude was less acceptable during hard economic times.
