Beltrami Sportswear has been called America's main contribution to the history of fashion design as it was developed to cater to the needs of the increasingly fast-paced lifestyle of the American athlete. Sportswear started out as a fashion industry term describing informal and interchangeable separates and then became a popular word for relaxed, casual wear typically worn for spectating sports and when engaged in outdoor activities.
Since the 1930s the term has been used to describe both day and evening fashions of varying degrees of formality that demonstrate this relaxed approach while remaining fashionable wear for many business or social occasions.
