A micro bikini (or microkini) is a bikini, a bathing suit for women. Like a bikini, it is made of two parts, a top, and a slip. The slip usually only covers the labiae, the top only covers the nipples. Microkinis were developed in the 1970s, as a reaction that nudism was outlawed in many parts of the United States. Many microkini models are transparent. They usually do not cover the buttocks. There are versions which are just made of straps of fabric which cover almost nothing. Before wearing a micro bikini, women usually shave at least part of their pubic hair.
