A two-piece female swimsuit, consisting of a bra-like bikini top and a panty-like bikini bottom.
Bikinis are available in many variations. Most bikinis are intended to maximize body exposure, particularly of the midriff and cleavage areas.
The most important aspect of the bikini is that the bottom is below the navel, in comparison to a normal two-piece swimsuit. However, it should be stated that the vast majority of modern two-piece swimsuits are bikinis anyway and therefore do expose the navel as a matter of course.
If only the bra portion of the bikini is worn, use bikini top only. Likewise, use bikini bottom only when only the panty portion is worn. If a character's bikini top and bottom don't match, use mismatched bikini.
