I have purchased other Capezio leotards that have been great, but this one ran much smaller than the others, and was actually see-through (I ordered it in white) I recommend ordering this a size up, and not in pink, white, or light blue. I absentmindedly got a small, though I know I prefer a bit of extra room. The size chart said I should get an extra small though! Exchanging the white one I ordered for a medium in Garnet.
EDIT: I received my new garnet leotard, and at first I thought it fit great! Then I noticed how awkwardly wide the crotch is. It bunches up because it is maybe 4 inches across. With a ballet skirt overtop this is not a problem, but worn solo it looks very weird.
