Wanting to list some girls sizes medium, large and extra large items. The catagories are by age. This makes no sense with bigger girls and boys. I have an 11 year old that wears the same size shirt as the 19 year old and am sure that is the case with lots of children. If I list a medium in the 10 - 12 year old catagory and someone with a 14 year old that wears a medium is not going to look in that catagory.

By the way, what are the tags listed below??
