Gorgeous - never been worn - Striped Skort

Gorgeous - never been worn - Striped Skirt with Shorts sewn in underneath (skort) Can't believe my daughter was not interested in wearing this. Perfect condition. Very soft! It says on the tag 4-5 year old. I can't figure out why. Makes no sense. It fits my daughter now at age 10, though she is skinny. I would say probably ages 7-9 for average weight.
