How did activewear develop?

Activewear developed in response to the increasing popularity of fitness and sports in the late 20th century, particularly during the 1980s fitness boom. Innovations in fabric technology, such as moisture-wicking and stretchable materials, made clothing more functional and comfortable for physical activities. Additionally, the rise of athleisure as a fashion trend blurred the lines between athletic and casual wear, further driving the demand for stylish yet practical activewear. Today, it encompasses a wide range of clothing designed for both performance and everyday wear.
