A bikini is typically a women's two-piece swimsuit featuring two triangles of fabric on top, similar to a bra and covering the woman's breasts, and two triangles of fabric on the bottom, the front covering the pelvis but exposing the navel, and the back covering the buttocks. The size of the top and bottom can vary from full coverage of the breasts, pelvis, and buttocks, to very skimpy designs like a thong or G-string that cover only the areolae and mons pubis, but expose the buttocks.

Bikini is a Hungarian rock band.
