this leotard is nice and my daughter loved the style. It runs extremely small, and she can't wear it, so I have to send it back. Normally, she is a size 10-12, so she is between a child medium and large. I ordered a large and the size says 12-14 on the tag, but she could barely stretch it on, and it pulled on her shoulders. She really likes the style, so I'm going to order an adult small and hope that one fits.
