What fashion fad did the 1983 film "Flashdance" make popular?

The 1983 film "Flashdance" made leg warmers a popular fashion fad.\n\nLeg warmers were originally practical knit coverings worn by dancers to keep calf muscles warm during rehearsals. After Jennifer Beals appeared as Alex Owens wearing dancewear, leg warmers, and an oversized off-the-shoulder sweatshirt, the accessory moved from studios and fitness classes into everyday 1980s fashion.\n\nThe movie did not invent leg warmers. They had already appeared in dance culture and were also associated with films such as "Fame" and "Xanadu," as well as the era's growing aerobics craze. "Flashdance" helped make them mainstream, where people paired them with leggings, leotards, miniskirts, and oversized tops.\n\nA common mix-up is to answer "off-the-shoulder sweatshirts" or "ripped sweatshirts." Those looks were also strongly associated with the film, especially its famous poster, but the standard single-answer trivia response to this question is leg warmers.
