Even though I exercise or play sports almost everyday, I don't have a lot of different workout clothes. Mostly repetitions of the same thing. If I like the fit, I buy more than one. Body by Gap t-shirts, a danskin or champion sports bra, bebe sport shorts, bebe sport capri leggings, Nike dri-fit long running pants and Nike sports jackets. I think I look stylish because the clothes fit me well (form fitting), they're clean and simple styles, and I look healthy.
The bebe sport shorts and leggings I have keep me dry, the don't soak up perspiration like for unsightly wet spots. They really do function as workout clothes and I work out pretty vigorously for up to two hours. I was a bit surprised, because I didn't expect them to be functional and cute.
