When did the bikini come out?

The bikini was introduced on July 5, 1946, by French designer Louis Réard. It made its debut during a fashion show at the Piscine Molitor in Paris, and its name was inspired by the Bikini Atoll, where nuclear tests were conducted, suggesting that the swimsuit would create a splash in the fashion world. The design was initially controversial and faced significant social backlash before eventually gaining popularity in the 1960s.
