The 1920s was the decade in which fashion entered the modern era. It was the decade in which women first liberated themselves from constricting fashions and began to wear more comfortable clothes (such as short skirts or pants). Men likewise abandoned overly formal clothes and began to wear sport clothes for the first time. The suits which men wear today are still based, for the most part, on those which were worn by men in the late 1920s.

The 1920s were characterized by two distinct periods of fashion. The early 1920s where nature and change progressed slowly as many were reluctant to adopt the new styles. From 1925, the styles that have been associated with the Roaring Twenties were passionately embraced by the public and would continue to characterize fashion until early in 1932.
