I got this and really like them! I wore them twice already and they fit very comfortable. I wash them and they did not shrink or anything, the material is soft and really allows flexibility when exercising. It also seems to be true to size, I am  5'6 and weight 126 pounds and the size small fits well. I do have to say, that at times when bending down, the pants tend to come down a tiny bit-not to the point that your butt is showing, but still wish they would not do that. They do not come down much, so it really comes to down to personal preference. Another thing, if you are really having a hard core workout and sweat a lot (like I did today wearing these pants) the sweet is visible. I mean  the pants are black, but still don't like the fact that it shows. Anyway, overall, very comfortable and reasonably priced! Ohhh and they really make your legs and butt looks nice :)!

UPDATE 02/16/13- Do not buy these pants if you do hardcore workouts at the gym and sweat a lot. Although I like how these pants fit me, I HATE the fact that the sweat is visible!!! It is kind of embarrassing. I think this pants are made for light workouts and just for running quick errands during the day..
