The top does run tighter than the bottom, as the other reviewer stated. I ordered the medium, as I typically wear a large in dance wear but have a short torso. (155lbs, 5'9", 37 bust, 30 waist, 41 hip, 60 girth). It's really snug through the shoulders but I can get it on. The top is beautiful, which was so enticing about it in the first place.
The problem is that the shorts don't stay put. The band at the bottom is VERY tight, which in itself makes an ugly, uncomfortable line. But the fabric around the legs is much looser than the band (it's not a uniformly snug fit, in effect; the band is just super tight). So it rides up. Really really badly. You can only wear really loose sweats over it, because a skirt or leggings would look completely ridiculous (gobs of bunched fabric around the legs). And it's rather uncomfortable in the crotch area to have all of that fabric bunched up. It basically rides up to where a leo line would be, exposing half the bum, but with crazy amounts of extra fabric to deal with. Ridiculous.
For the record, the inseam on the medium is 2.5 inches. But be warned, it wasn't until I wore the thing that I realized how it would ride up, which of course was too late to return it!
Fits very well. The top portion is tighter than bottom. Once on, it's like a glove...unmovable, which is great for long periods of dancing.
I ordered Large. My measurements are 36 - bust, 46 - shoulders, waist - 29, so if you are larger than that, the top SECTION may be too small.
I would like to see more colors....red would be nice :)
