Micheline Bernardini models the first modern bikini at a swimming pool in Paris.

Micheline Bernardini is a French former nude dancer at the Casino de Paris who agreed to model, on 5 July 1946, Louis Réard's two-piece swimsuit, which he called the bikini, named four days after the first test of an American nuclear weapon at the Bikini Atoll.

A bikini is a two-piece swimsuit that features one piece on top that covers the breasts, and a second piece on the bottom: the front covering the pelvis but usually exposing the navel, and the back generally covering the intergluteal cleft and some or all of the buttocks. The size of the top and bottom can vary, from bikinis that offer full coverage of the breasts, pelvis, and buttocks, to more revealing designs with a thong or G-string bottom that covers only the mons pubis, but exposes the buttocks, and a top that covers only the areolae. Bikini bottoms covering about half the buttocks may be described as "Brazilian-cut".
