It took fifteen years for the bikini to be accepted in the United States. In 1951 bikinis were banned from the Miss World Contest. In 1957, however, Brigitte Bardot's bikini in And God Created Woman created a market for the swimwear in the US, and in 1960, Brian Hyland's pop song "Itsy Bitsy Teenie Weenie Yellow Polka Dot Bikini" inspired a bikini-buying spree. Finally the bikini caught on, and by 1963, the movie Beach Party, starring Annette Funicello (emphatically not in a bikini, by mentor Walt Disney's personal request) and Frankie Avalon, led a wave of films that made the bikini a pop-culture symbol.

People who are familiar with the history of Bikini Atoll—particularly opponents of nuclear proliferation—may find the etymology and use of the word "bikini" for a garment as inappropriate, as its tongue-in-cheek "explosive" reputation effectively reduces the significance of a serious historic humanitarian crisis—one that still influences the politics of the Marshall Islands—to a mere popular culture sex symbol in the minds of most people. The term two-piece is considered a neutral alternative. The Miss World pageant is an international beauty pageant founded in the United Kingdom by Eric Morley in 1951.

Opposition to the wearing of bikinis led to their replacement with more modest swimwear after the first contest. In 1959, the BBC started broadcasting the competition. The pageant's popularity grew as the popularity of television grew.
