Here is a handsome long sleeve button down shirt by Manhattan. Tealy blue shirt with vertical stripes of maroon, black, and olive green. Seven button front, two on each cuff, one on each wrist, and a pocket on the left breast. It's in 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) 21"
Shoulder to end of sleeve (including cuff) 24"
Length 31"

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