The history of the bikini is fascinating:

• The invention of the bikini was driven in part by war-time rationing of fabric during WW2.
• It was called the bikini after the atoll on which the US tested nuclear missiles. Like the atom bomb it was “small and devastating”.
• The name also fit because before the bikini the most popular swimsuit was a one-piece called the atom. Just like the bomb, the bikini “split the atom” into a two piece.
• There are various bikini styles, but its creator thought that the best ones revealed “everything about a girl except for her mother’s maiden name”.
