Young Curly Brunette Girl Strips Her Black Bikini On The Rocky Shore At The Sea

Types of underwear worn by both men and women are identified as bikini underwear, similar in size and revealing nature to the bottom half of a bikini bathing suit. For women, bikini underwear can refer to virtually any tight, skimpy, or revealing undergarment that provides less coverage to the midsection than traditional underwear, panties or knickers. For men, a bikini is a type of undergarment that is smaller and more revealing than men's briefs.
