Here is a cool vintage button down shirt by Sir Walter. It's a 50/50 poly and cotton blend. Wonderful salmon colored fabric. Seven button front and a pocket on each breast. Nothing super fancy, just timeless good looks. Thin, fairly sheer, soft, and comfy. It's in amazing condition with years of life left! The tag says Medium, but here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 22"
Shoulder to end of sleeve (including cuff) 9"
Length 30"

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