Here is an awesome vintage Polo shirt by Nui Nalo of Hawaii. It's a blend of acetate and nylon, and made in the USA. Brown shirt with super cool Hawaii themed cool graphics on the front and back. Three button collar with a pocket on the left breast. Medium weight and soft. Lots of cracking in the graphic, but it doesn't appear to be peeling off. It's in otherwise excellent shape with tons of life left! The tag says Medium, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 20"
Shoulder to end of sleeve (including cuff) 9"
Length 28"

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