I am also a huge Athleta fan, especailly for their running/hiking/yoga bottoms. I can't wear tradtional jogging shorts (never, not even when I weighed 95), as they just don't flatter me. I bought a pair of Athleta running shorts that have the lycra short under the jogging shorts (attached) and i love them. I also have quite a few of their exercise tanks and dresses!
However, I do't do so well when I go to the store. It feels overwhelming and they don't have petite sizes there. That was my original purpose for buying from them. I wish they had petite sized tops/sweaters. I've bought a few of their casual/city type tops and even the xx smalls are too big in the arms. I can wear the tanks, though.
