Review on Danskin Girls Theatrical Intermediate Medium Girls' Clothing: Unleash Your Talents with Our Perfect Fit by Derick Carpenter

I bought this for my 4 year old's ballet class, I hesitate to choose between these two size options when ordering as it's on the middle and her normal dress size is 5-6. I chose 2-6X as I think you don't want her to slip while dancing do you? It's quite stretchy, stretchy enough to fit 2-6 years old. And it's good quality too! Very cute pack.
