The bikini is named after the "Bikini Atoll", an island where the United States conducted tests on atomic bombs.

The story behind the answer

True. The swimsuit was named after Bikini Atoll in the Marshall Islands, where the United States began nuclear bomb tests in 1946 (Operation Crossroads). French designer Louis Réard introduced the revealing two-piece on July 5, 1946, and chose “bikini” to suggest it would create an “explosive” reaction in fashion, just like the tests had shocked the world.

Bikini Atoll’s residents were displaced, and the tests left lasting environmental and health impacts—important historical context behind a common word. To remember: tiny swimsuit, big name—borrowed from a small Pacific atoll made globally famous by massive explosions.
