Book excerpt: Fashion is synonymous with change yet the iconic showgirl costume--feathers, sparkle and revealing clothes--has remained largely unchanged since the early 20th century. Beginning in the 1800s, a couture of the risque evolved from Paris nightclubs to Las Vegas casinos. The concept of glamour itself was based on what Parisian courtesans and burlesque performers wore. A tall pretty girl with headdress, nude core with spangles, high heels and dramatic makeup became a Gallic symbol and later the trademark of Hollywood musicals. France exported costumes and millinery--as well as whole productions from the Moulin Rouge, the Lido and Folies Bergere --to the U.S. and the world. More recently, cabaret styling has translated into today's day, sport and evening clothes.
