The 1920's, probably the most daring decade for men and women alike, revolutionized the fashion world. With the arrival of the 'jazz age' and prohibition, women's skirts rose scandalously to the knees, the hair was cut short in a boyish bob, women shamelessly smoked and drank in public and defied the rigid social status that the early 1900's brought.
The waist lines of the dresses dipped to the hips and braziers were worn to bind the breasts giving women a boyish look; a look that commanded power and equality with men. A look called 'The Flapper'.
Men's fashion didn't change much in the twenties; if anything, it became more tapered. The trousers tapered down tightly at the ankles. Fedoras were a major fashion statement of the dashing man, and with the arrival of gangsters like Al Capone, pin-striped suits came into fashion.
