Walt Disney Minnie Mouse shirt size girls XL 16 dated 2018

This is a navy blue shirt with white stars on the front and back. It has 8 or so rhinestones on the front and a white Minnie Mouse face on the lower right hand side of the shirt. It is short sleeves, girls size XL 16, dated Walt Disney World 2018. Purchased in a Walt Disney World boutique. I tried it on and it was too small for me.
