As an adult dancer with a long torso (my chest/waist/hip dimensions are usually a small/medium and my girth at the end range for lg), I have a very hard time finding pretty leotards that fit me. Because other reviews said this leo ran small, I tried both a medium and a large. I actually found that the leo ran a little big compared to other brands. For instance, I tried the Bloch Ballon, which has a similar cut, and the medium was much tighter and shorter. But the medium in this style fit very comfortably in the torso. And it fit perfectly girth-wise creating a smooth leg/hip line :-) The reason I returned it was because the sleeves were loose on me, and I wanted a more fitted look. It's such a flattering leo that I will eventually try the small.
I ordered a large because the reviews said it ran small. I usually order a medium. Large was a perfect fit. I have worn it for yoga and also as the top to a festive holiday skirt! Just perfect
Too small for a medium. They should say it runs small. Medium is like Xtra sm waste of money very unhappy
