It runs small. The size I is super tight on my just 6 year old daughter. I guess I should have bought her a size M 8-10. This one should last her a couple months. I will know for next time. Either way it is so pretty on.
Just received this leotard. Looks cute and is exactly what my daughter is looking for, runs small. My daughter used to be always on the tall/skinny side of her age (almost 9). The size M fits just right with no room to grow. Thinking that I should've ordered the L instead. But, when I measured her "girth" she fell in the M based on the size chart above.
The quality of the fabric and style are great, however it runs a little large around the legs. While the top and body fit fine the legs had gaps. Fortunately, these were easily fixed with a couple of tightening stitches. Overall great product!
