Bikini Day

Bikini Day coincides with the invention of the bikini in 1946. The revealing bathing suit worn by women around the world is named after the Bikini Atoll in the United States, where atomic tests were carried out. The French costume designer originally wanted to call the separating pieces of fabric an ‘atom’, but the word ‘bikini’ caught on much better.


As early as World War II, sunbathers began to ditch closed, chaste bathing suits in favor of lighter and simpler, usually two-piece beachwear. However, American women did not appear on the beach after the 1946 innovation – until the 1960s, bikinis were banned. Europe was enthusiastic about the new fashion and did not introduce such bans.

Soon in the 1960s, movie stars such as Ava Gardner and Brigitte Bordeaux began to appear in newly designed swimsuits. Actresses wore bikinis in films, as well as for ordinary trips to the beach.
