Book excerpt: The 1950s was the first decade when American fashion became truly American. The United States had always relied on Europe for its style leads, but during World War II, when necessity became the mother of invention, the country had to find its own way. American designers looked to what American women needed and found new inspirations for American fashion design. Sportswear became a strength, but not at the expense of elegance. Easy-wear materials were adapted for producing more formal clothes, and versatile separates and adaptable dress and jacket suits became hallmarks of American style. This book follows the American fashion industry from New York's 7th Avenue to the beaches of California in search of the clothes that defined 1950s American fashion.
