I love So Danca leotards because they are reliable in fit and fabric without breaking the bank. I am 5'1", 120lb and based on my measurements, ordered an adult medium in the light pink color. It fits very comfortably (my only small complaint is that the sides come up pretty high into my armpit, probably because I am just a mere mortal and not a professional dancer - I am guessing these are designed for taller/leaner folks. :) The pink is very pretty- a bit on the cooler side (which i prefer and find more flattering), as opposed to the dusty ballet pinks you sometimes see in the ballet gear world. I'm not sure if this is only the lighter colors, but it is lined in the front, and the wider strap feels supportive. A new favorite!
