I bought a 14/16 because most of the size 12's don't stretch which my daughter is comfortable in but I could go down a size and she would still love it. This size fits her just right, it's a bit big but nothing special, it allows her to grow all year round without having to buy tons of new clothes. Just to clarify, my daughter is almost 6 years old. 4 feet 2 inches and weighs 75 pounds. She's taller for her age and still getting used to going to the bathroom by herself so needs a looser dress.
