The late 1950's and early 1960's era saw the introduction of some huge designers. Christian Dior popularized the wearing of the A-line skirt. The 1950's ushered in the wearing of trousers for women, and high heels often had a rounded or peep toe. In the early 1960's the miniskirt was invented, and the pillbox hat gained popularity. Box shaped PVC dresses and go-go boots were in high fashion.
