these fit great! 5'6, 150 lbs, somewhat curvy/athletic build and the 7 fits perfectly. lots of stretch, not too low cut. as others have said, don't love the back pockets, but i can ignore that. very stretchy and comfy. the only reason for the 4 starts instead of 5, the way a lot of the stitching inside is a bit scratchy. i am hoping it will soften with wash and wear, but in a few spots it was really poking me.
