What were women's fashions like after World War 1?

women's fashions drastically changed. dresses went from the ankle to knee length. the look women wanted was the boyish athletic look. short hair, long skinny legs, flat chests (busty women would wrap their chests to make them look flat chested) the backs of dresses went from covering up their entire back to an extreme low back to show off their shoulder blades, which it seems were quite the fashion.
