J.C. Penney: Not just for grandmas looking for their next Christmas sweater anymore! I recently wandered in on a whim and was amazed by how diverse and, yes, stylish their Xersion line of workout gear is. With new stock arriving every other month or so, there's plenty of variety, and the older stuff goes to clearance quickly—you can pick up a sweat-wicking top for as little as $6. Even better, the quality is great. I've been wearing them for years now and my J.C. Penney running capris have outlasted my much pricier pair from a very popular brand.
