Love the style of this leotard. I ordered for my daughter who usually wears between and I and an M. Based on another review, I ordered the I, but we found this leo to run on the small side, so have to exchange for a M. While she could get into the I, she couldn't raise her arms comfortably. This is perfect for her ballet classes.
The cutout in the back is adorable and the fit is great. Bloch leotards are my daughter's favorite because of how soft they are. The quality is excellent as well. She has several that are over two years old and they are still in great condition.
