Bikini introduced On July 5, 1946, French designer Louis Réard unveils a daring two-piece swimsuit at the Piscine Molitor, a popular swimming pool in Paris. Parisian showgirl Micheline Bernardini modeled the new fashion, which Réard dubbed "bikini," inspired by a news-making U.S. atomic test that took place off the Bikini Atoll in the Pacific Ocean earlier that week. European women first began wearing two-piece bathing suits that consisted of a halter top and shorts in the 1930s, but only a sliver of the midriff was revealed and the navel was vigilantly covered. In the United States, the modest two-piece made its appearance during World War II, when wartime rationing of fabric saw the removal of the skirt panel and other superfluous material. Meanwhile, in Europe, fortified coastlines and Allied invasions curtailed beach life during the war, and Swimsuit development, like everything else non-military, came to a standstill. In 1946, Western Europeans joyously greeted the first war-free summer in years, and French designers came up with fashions to match the liberated mood of the people. Two French designers, Jacques Heim and Louis Réard, developed competing prototypes of the bikini. Heim called his the "atom" and advertised it as "the world's smallest Bathing Suit." Réard's swimsuit, which was basically a bra top and two inverted triangles of cloth connected by string, was in fact significantly smaller. Made out of a scant 30 inches of fabric, Réard promoted his creation as "smaller than the world's smallest bathing suit." Réard called his creation the bikini, named after the Bikini Atoll. In planning the debut of his new swimsuit, Réard had trouble finding a professional model who would deign to wear the scandalously skimpy two-piece. So he turned to Micheline Bernardini, an exotic dancer at the Casino de Paris, who had no qualms about appearing nearly nude in public. As an allusion to the headlines that he knew his swimsuit would generate, he printed newspaper type across the suit that Bernardini modeled on July 5 at the Piscine Molitor. The Solid Bikin was a hit, especially among men, and Bernardini received some 50,000 fan letters. Before long, bold young women in bikinis were causing a sensation along the Mediterranean coast. Spain and Italy passed measures prohibiting bikinis on public beaches but later capitulated to the changing times when the swimsuit grew into a mainstay of European beaches in the 1950s. Réard's business soared, and in advertisements, he kept the bikini mystique alive by declaring that a two-piece suit wasn't a genuine bikini "unless it could be pulled through a wedding ring." In prudish America, the bikini was successfully resisted until the early 1960s, when a new emphasis on youthful liberation brought the Beach Swimsuit en masse to U.S. beaches. It was immortalized by the pop singer Brian Hyland, who sang "Itsy Bitsy Teenie Weenie Yellow Polka-Dot Bikini" in 1960, by the teenage "beach blanket" movies of Annette Funicello and Frankie Avalon, and by the California surfing culture celebrated by rock groups like the Beach Boys. Since then, the popularity of the bikini has only continued to grow. The garments we wear when swimming in pools, the ocean, or other bodies of water are commonly known as "bathing suits", but why? Where did this name originate? The simple answer to that question is that Beach Bathing Suits are named for the English spa city Bath. What is the difference between a "bathing suit" and "swimwear", or "swimsuit"? These terms are used interchangeably in Styling by the Sea but may be differentiated when encountered in other in places. Swimsuit – an item of clothing designed to be worn by people engaging in a water-based activity such as swimming, diving, and surfing, or sun-orientated activities, such as sunbathing. Some users associate the term exclusively with a woman's bathing suit and usually only refers to a woman's bathing suit. Bathing suit – most general term, gender-neutral, applies to anything someone might wear while swimming. Swimwear – also gender-neutral, but often used in department stores or in the context of distinguishing among other types of clothing lines (sportswear, formal wear, et Swimming trunks – refers to men's bathing suits only, it's understood, but sounds a bit outdated.
