Sportswear is an American fashion term originally used to describe separates, but which, since the 1930s, has come to be applied to day and evening fashions of varying degrees of formality that demonstrate a specific relaxed approach to their design, while remaining appropriate for a wide range of social occasions.
 The term is not necessarily synonymous with activewear, clothing designed specifically for participants in sporting pursuits.
 Although sports clothing was available from European haute couture houses and "sporty" garments were increasingly worn as everyday or informal wear, the early American sportswear designers were associated with ready-to-wear manufacturers.
 While most fashions in America in the early 20th century were directly copied from, or influenced heavily by Paris, American sportswear became a home-grown exception to this rule.
 Sportswear was designed to be easy to look after, with accessible fastenings that enabled a modern emancipated woman to dress herself without a maid's assistance.

Thomas Franklin Brigance (February 4, 1913 – October 14, 1990), professionally known as Tom Brigance, was a Texan-born New York-based fashion designer noted for his work in sportswear in the 1930s, 1940s and 1950s.
 As a house designer for Lord & Taylor, Brigance was best known for bathing costumes and play clothes, and for his clever use of flattering details such as pleats and darts.
 During the 1930s Brigance was a rare example of a male working in the female-dominated world of American sportswear design.
 In the late 1930s, he was regularly mentioned alongside Clare Potter as a leading name in mid-range priced sportswear.
 Like Potter, Brigance was skilled at to designing smart, fashionable clothing which could easily be mass-produced, making his work attractive to manufacturers as well as to customers.
Sydney Wragge (1908-1978) was an American fashion designer active during the 1940s, 1950s and 1960s.
 Working as B.H. Wragge, he was particularly renowned for his American sportswear, with the historian Caroline Rennolds Milbank declaring him the leader in mix-and-match separates and interchangeable wardrobe design.
 In the 1930s and 1940s, Wragge, along with John Weitz, was one of the few male "pioneers" in the female-dominated world of early American sportswear design.
 The fashion journalist Sally Kirkland, looking over the development of American sportswear, compared Wragge's design ethos to that of a later designer, Ralph Lauren, declaring that they shared impeccable taste and an eye for the best possible fabrics and prints.
 He was known for his versatile work, offering jackets that worked with both full and narrow skirts, and two-piece dresses that worked equally well as interchangeable blouses and skirts.
 In the 1960s, he updated his work to successfully meet the demands of the next generation for even more practical, pared-down clothing.
 When curating his major exhibition of American sportswear for the Metropolitan Museum of Art in 1998, Richard Martin noted that many of Wragge's former customers still retained the capsule wardrobes they had originally bought in the 1940s and 1950s.

Anne Fogarty (February 2, 1919 – January 15, 1980) was an American fashion designer, active 1940–80, who was noted for her understated, ladylike designs that were accessible to American women on a limited income.
 She started out as a model in New York in 1939, working for Harvey Berin on Seventh Avenue, before studying fashion design.
 She eventually secured a full-time design job in 1948, and became well-known for full-skirted designs with fitted bodices, inspired by Dior's New Look.
 Her clothes were easy to wear, practical, and made in casual fabrics, following the American sportswear tradition.
 She ran her own label from 1962 to 1974, and worked as a freelance designer until her death.
 In 1959, Fogarty published a style manual, "Wife Dressing: The Fine Art of Being a Well-Dressed Wife", which emphasized femininity, neatness, and always being suitably dressed as desirable qualities.
 "Wife Dressing" was rediscovered in the early 21st century, and has become a key resource for designers and fashion historians looking to explore the 1950s ideology of ultra-feminine dressing.

Clare Potter was a fashion designer who was born in Jersey City, New Jersey in 1903.
 In the 1930s she was one of the first American fashion designers to be promoted as an individual design talent.

 Based in Manhattan, she continued designing through the 1940s and 1950s.

 She founded a ready-to-wear fashion company in Manhattan named "Timbertop" in 1948, and in the 1960s she also established a wholesale company to manufacture fashions.
 Potter was one of the 17 women gathered together by Edna Woolman Chase, editor-in-chief of "Vogue" to form the "Fashion Group International, Inc.", in 1928.
