I bought this because the product listing says US size, my daughter is a size 5-6 for girls. The item description lists the size and age range with the size number on the tag (5-6x is tag size 140 which means it is suitable for 7-8 year olds according to the item description). There is no size conversion anywhere, which is reflected in the sizing options you can choose from. I will not return, I can give to my niece. I'm disappointed because my daughter was happy about it.
