Mens fashion of the 1920s showed a a sharp and unique contrast to those of the previous decades.
At the end of WWI, men came home to find their closets full of clothes that were outdated.
The soldiers returned to the "Edwardian" and Victorian wardrobes they had left before the war.
These clothes didn't reflect the progress of technology, marketing, and individualism that marks the 1920s as a unique decade in American history.
Though the shift in mens fashion was not as pronounced as that of women's fashion movement.
Men's fashion changed rapidly as the 1920's progressed.
It moved away from the stuffy conservative suits of the previous fashion eras, to a more "masculine" and individualistic approach to men's suits.
