Here is an awesome vintage T-shirt by San Jorge. 65% cotton, 35% poly, and made in Mexico. Dark blue shirt with great Puerto Vallarta graphic on the left breast. Medium weight, and super soft and comfy. This one is in excellent condition with tons of life left. The tag says 46, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 18"
Shoulder to end of sleeve (including cuff) 8"
Length 26"

This item is sold from a vintage boutique in Roanoke, VA.
