Here is a super handsome short sleeve button down shirt by Guaya-Teca. 80% polyester, 20% cotton, and made in Mexico. This is the best looking one of these I've seen in person. Off white, ecru shirt with amazing stitching and embroidered details throughout. Buttoned collar, five button front, random buttons elsewhere, and a pocket on each hip. Super light weight, thin, and soft. It's in excellent condition with tons of life left. The tag says Medium, but here are the exact measurements taken laying flat. (Please see the last picture to see how we measure shirts)

Chest (armpit to armpit) 22"

Shoulder to end of sleeve (including cuff) 10"

Length 27"
