During the 1920s, women celebrated the new social and financial freedoms gained during World War I by adopting a new look characterized by short "bob" hairstyles, loose and shorter clothing allowing for greater movement, and less restrictive undergarments. Known as "flappers", these young women rebelled against pre-war conventions through behaviors like smoking, dancing, and more open attitudes towards sex and relationships. Their fashionable but informal styles, epitomized by designers like Coco Chanel, represented a shift towards modernity and a new era of women's liberation.
