Review on Footed Girls' Ballet Tights: Stylish Leggings for Girls in Socks & Tights Department by Sasha Hsiao

Very thick material so not sure if it stretches well. If your child is taller, I would probably recommend going up to the next size up. My daughter hates wearing anything tight and the belt is a little stretchy but difficult to stretch. So if your child likes it a little looser and closer to the next size up, go for size 1.
