Bikini

Bikini typically refers to a two-piece women's swimsuit. In 1946, the term "bikini" was coined by Louis Réard, who named the swimsuit after Bikini Atoll, where testing on the atomic bomb took place. Reard chose the name “bikini” because he believed the suit's revealing style would create a stir among people similar to their shock and surprise in response to America’s atomic bombing of Japan the previous summer. One part of the attire covers the breasts and the other part covers the groin and part of or the entire buttocks, leaving an uncovered area between the two. Merriam–Webster describe the bikini as "a woman's scanty two-piece bathing suit" or "a man's brief swimsuit." It is often worn in hot weather, while swimming or sunbathing. The shapes of both parts of a bikini resemble women's underwear, and the lower part can range from revealing thong or g-string to briefs.
