Wearing Your Gym Clothes in Public Is No Longer a Fashion Faux Pas

Maybe high-fashion trainers were the jumping-off point, but if you ask Karl Lagerfeld, designers have finally lost control and started making really stylish sweats (Karl included). This year saw the rise of a brand-new trend in the industry — fashion-friendly activewear lines that are as chic as they are functional — and they're not going anywhere anytime soon.

Net-a-Sporter's launch this Summer was one of the first high-end fashion retailers to offer a section entirely devoted to designer yoga pants, hoodies, swimwear, and even sweatbands, but they certainly weren't the last. Since then, we've seen sportswear edge its way into the fashion arena even more prominently, like Athleta's runway spot during NYFW. And, with lines coming from everyone from Betsey Johnson to Selena Gomez, you're about to see a lot more of the style set in their gym clothes — and a lot more well-dressed gymgoers, too. Scroll through for a look at all the style-conscious activewear labels you'll want to add to your own closet.
