Sportswear has been called America's main contribution to the history of fashion design. The term became popular in the 1920s to describe relaxed, casual wear typically worn for spectator sports. Since the 1930s the term is used to describe both day and evening fashions of varying degrees of formality that demonstrate this relaxed approach while remaining appropriate wear for many business or social occasions. This term also refers to clothing designed for participants in sporting pursuits and activewear, see Sportswear (activewear).

Sportswear started out as a fashion industry term describing informal and interchangeable separates (i.e., blouses, shirts, skirts and shorts), but now describes clothing worn for a wide range of social events. It was developed to cater to the needs of the increasingly fast-paced lifestyle of American women. The early sportswear designers were associated with ready-to-wear manufacturers, rather than haute couture houses. The clothes were intended to be easy to care for, in easily washable fabrics, with accessible practical fastenings, to enable the modern, increasingly emancipated woman to dress herself without a maid's assistance. While most fashions in America in the early 20th century were directly copied from Paris, designer sportswear was the exception to this rule, being an American invention.
