Tight fitting; worn for swimming; SYN. bathing suit, swimming costume, bathing costume.
One-piece stretch body garment worn by women for swimming. Introduced in the late 19th century, the swimsuit originally consisted of two garments—a long tunic and knickers— and was made of serge or wool. The one-piece garment became popular around 1900. The introduction of elasticized synthetic and fast-drying fibers subsequently enabled more flexible swimsuits to be developed.
