: a woman's two-piece swimsuit consisting of bikini briefs and a tank top

Did you know?

The two-piece swimsuit we call the bikini made its debut on Paris runways in 1946. The word bikini comes from Bikini atoll, the name of one of the Marshall Islands in the western Pacific, where atomic-bomb tests were performed in 1946. One theory of the coinage is that the effect achieved by a scantily clad woman appearing in public may be compared to the effect of an A-bomb blast. Another possible explanation is that the bikini leaves its wearer nearly bare, the way the bomb tests stripped Bikini atoll. In 1985, the tankini began appearing on beaches in the U.S., and the word bikini was combined with tank to create its appropriate name.
