Day Of The Underwear, New York City, United States

Meanwhile, some women adopted the corset once again, now called the "waspie" for the wasp-shaped waistline it gave the wearer. Many women began wearing the strapless bra as well, which gained popularity for its ability to push the breasts up and enhance cleavage.
• 1950s and 1960s
In the 1950s, underwear manufacturers began marketing printed and coloured undergarments. What had once been a simple, white piece of clothing not to be shown in public suddenly became a fashion statement. Manufacturers also experimented with rayon and newer fabrics like Dacron, nylon and Spandex. By 1960, men's underwear was regularly printed in loud patterns, or with messages or images such as cartoon characters.
Women's undergarments began to emphasize the breasts instead of the waist. The decade saw the introduction of the bullet bra pointed bust, inspired by Christian Dior's "New Look", which featured pointed cups. The original Wonderbra and push-up bra by Frederick's of Hollywood finally hit it big. Women's panties became more colourful and decorative, and by the mid-1960s were available in two abbreviated styles called the hip-hugger and the bikini (named after the Pacific Ocean island of that name), frequently in sheer nylon fabric.
