I say these fit "somewhat small," but I say that because they are super low-rider.  They fit very strangely and low up top.  The legs, however, have plenty of room and will stretch more than I needed them to.  There isn't any controlling or firming action in these.  And they are sheer just like so many other inexpensive leggings.  I wanted to love them because I do really like the pattern of the red with the black cats, but the fit was just too strange.  The photo shows one of the black cat's heads falling right at the crotch where you can see ears (which I thought was kind of funny), but the pair I got didn't quite line up like that, and it looked like a different kind of kitty was at the crotch, if you know what I mean ( LOL--  Not the best place for a black triangular shape).  ;p.
