Here is a cool vintage button down shirt. It's 65% poly, 35% cotton. White fabric with brown stripes and a subtle diamond pattern throughout. Seven button front, one on each cuff, and a pocket on the left breast. This one is in amazing condition. Soft, light weight, with years of life left! The tag says 15 1/2 - 33, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 22"
Shoulder to end of sleeve (including cuff) 24"
Length 33"

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