A bodysuit is a one-piece form-fitting or skin-tight garment that covers the torso and the crotch, and sometimes the legs, hands, and feet, and cannot be used as a swimsuit. The style of a basic bodysuit is similar to a one-piece swimsuit and a leotard, though the materials may vary. A bodysuit, unlike a swimsuit or leotard, has snaps, hooks or velcro at the crotch. Thong or T-front thong bodysuits usually have the crotch opening moved up to the front to underbelly area to increase the wearer's comfort. A bodysuit may have sleeves and varying shoulder strap and collar styles. Bodysuits can be made from a number of fabrics, including cotton, lace, nylon, etc. In general, textile bodysuits include expandable fiber such as spandex for a better fit to the shape of the body.
