Skimpy swimwear is a term used to describe swimsuits that are designed to show off the body. Two of the most popular types of skimpy swimwear are Speedos and thongs. Speedos are tight-fitting swimsuits that cover the groin area and buttocks, while thongs are even skimpier, covering only the groin area. Both Speedos and thongs are popular choices for those who want to show off their bodies while swimming or sunbathing.
