Bikinis are two-piece women's swimwear made of lightweight, fast-drying fabric s styled with minimal coverage. The bikini bottoms generally have a low waistband that rests below the navel and a high-cut leg line. Back coverage depends on the style of the bikinis and can range from brief-style bikinis, which offer full back coverage, to thong bikinis, which offer minimal back coverage. The upper part may be made in a wide variety of designs including the classic bikini tops which features triangle cups with strings that fasten behind the back and neck.
