The idea of athleisure (wearing gym clothing as casual clothing) has been around for decades…before it was made popular by Alexander Wang and branded by the industry. Athleisure encompasses both comfort and style, while maintaining a casual yet cool look. In other words, you should go beyond just wearing sweatpants and a t-shirt; spruce it up. Treat the sweatpants as if you’re jeans or trousers, cuff the break. Pair it with some really cool loafers or broken-in leather boots. In a nutshell, don’t view it as gym clothes. Instead, think of it as any other outfit.
