Here is a cool vintage button down long sleeve shirt by Yves Saint Laurent. 65% poly, 35% cotton. Super handsome stripes of light brown, white, pink, and blue. Seven button front, one button on each cuff, pocket on left breast. In great shape with tons of life left! The tag says medium 14 1/2, 32-33, but here are the measurements. This shirt wouldn't button up, so I'd call it a small. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 19"
Shoulder to end of sleeve (including cuff) 24"
Length 31"

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