Although most dance leotards are small this one seems to work as expected. My daughter is 6 years old and wears a medium sized swimsuit. The medium/medium size of this backpack is a little big for her. Not too big for her but it annoys her because it keeps slipping down. If your child doesn't have a tummy when they've just donned a medium sized leotard, consider downsizing their size rather than getting a baby/medical tutu. It's so cute in person, and when she wore it to dance class with a simple black leotard, the teacher complimented her and asked where she got it! I like this one because it's a tutu but not as full and therefore looks a bit more grown up than the others.
