MODERN GYM CLOTHES

Need some motivation to get to the gym before spring gets here? American designer Derek Lam's collaboration with the athleisure brand Athleta will help you feel sporty and stylish. The Derek Lam 10C + Athleta collection is fit to wear inside or outside the gym. Some pieces are great to layer over gym clothes, others you can work out in. All of them have Lam's modern approach that will make you want to run errands after class just to show off. Here are a few of our favorites:
