MunsingWear Vintage Tropical Flower Shirt Yellow w/ Squares Men's Size M READ.

There are a couple spots where I can't tell if they're part of the pattern or if they're stains (they're like a beige color).  This issue is highlighted in the last couple pictures.  It is in otherwise good pre-owned condition.

Made of 100% Rayon.

This is like a light goldenrod color, and features squares of medium and dark gray, with white and blue hibiscus flowers in the foreground.

Chest measurement: 22" across (buttoned, flat, armpit to armpit).

Length: 29 1/2" from seam at center nape of neck to bottom of shirt hem.
