In the 1990s, Kate Moss wore an open slip dress that changed the way people dressed. This choice made a lot of noise and started a new trend because it stressed ease and a carefree style that wasn’t like the more structured styles that were popular at the time. A lot of people still wear slip dresses all the time because they look so classy and easy. Madonna was one of the first people to wear athleisure when it first came out in the late 1980s and early 1990s. She mixed gym clothes with everyday clothes a lot by going out in public in tights, crop tops, and track jackets. In the last few years, this style has become very popular, and now you can wear athleisure to both relaxed and dressy events.
