Since July 5, 1946, women have been hitting the beaches and pool sides in bikinis. National Bikini Day marks the anniversary of the invention of the revealing two-piece bathing suit.
Named after the Bikini Atoll, where the United States conducted atomic tests, the two-piece bathing suit made its debut in Paris. French designer Jacques Heim wanted to name revealing bits of fabric "atom," but designer Louis Réard named his piece the "bikini" and the name stuck.
