O'Neill Summer Cotton Shirt with Sun Pattern, Size XL

Cute, lightweight summer cotton shirt from O'Neill. Has a great sun pattern on it. No tears or stains. Size is XL, but it is rather small, so I am not sure if it is men's, women's or children's size. Please see measurements: Across shoulders @ 20", length in back @ 30", across chest @ 23.5", length in front @ 27", sleeve @ 9.25" (short sleeved). 100% cotton.
