Flapper was a term used in the 20s to refer to young women who wore
short skirts, bobbed their hair, and listen to Ragtime (later Jazz). They were considered the "new breed" of women, who could not only vote, but often would be seen wearing make up, drinking hard liquor, riding bikes, driving cars and even smoking.
The term comes from young birds flapping their wings eager to leave the nest.
The term was used as early as 1913 in England, and referred to girls in their teens. Later it came to include women under 30. By the 1920s it came to the United States, and came to mean a whole generation of women who reflected similar styles and attitudes. Such as the "mod women" of the 60s. (Marlo Thomas of That Girl was an example of the "mod" or "modern women" of the 60s)
Styles included a "boyish" bob of the hair and dying it jet black. Some went the other way and dyed it platinum blonde.
The flapper look grew and became more mainstream as the 20s went on. When the Great Depression took hold after October 1929, the style which was costly to maintain, crashed and almost disapeared overnight.
