A swimsuit is an item of clothing that is designed to be worn for swimming in. In Commonwealth English swimsuits are sometimes called togs (a term also used to describe clothing in general). Swimsuits can be skin-tight or loosely fitting and range from garments designed to preserve as much modesty as possible to garments designed to reveal as much of the body as possible without actual without clothes ity. Swimsuits are often lined with a fabric that prevents them from becoming transparent when wet.
In the ancient mediterranian, swimming and bathing was most often done without swimsuits, but without clothes e. In some settings coverings were used. Murals at Pompeii show women wearing two-piece suits covering the areas around their breasts and hips in a fashion remarkably similar to a bikini of c. 1960. After this, the notion of special water apparel seems to have been lost for centuries.
In the 18th century women wore "bathing gowns" in the water; these were long dresses of fabrics that would not become transparent when wet, with weights sewed into the hems so that they would not rise up in the water. The men's swim suit, a rather form-fitting wool garment with long sleeves and legs similar to long underwear, was developed and would change little for a century.
