The modern bikini was introduced by French designer Louis RĂ©ard on July 5, 1946, at a popular swimming pool in Paris. Named after the Bikini Atoll, where post-war nuclear testing was taking place, the bikini revolutionized women’s swimwear with its bold design that exposed the belly button for the first time. Despite initial controversy and skepticism, the bikini gradually became a global fashion staple, symbolizing freedom and confidence in women’s beachwear fashion.
