This mid century shirt is lightweight  with a nylon blend, micro meshy fabric with a zig zag op art pattern.  The buttons are pretty pearlized buttons,, one has been replaced.

size:  the chest is approx 40" (20 " across seam to seam under the arms)
NOTE:  the underarm to shoulder measurement is a bit tight..9.5" inches underarm to shoulder, x 2 = 19" circumference.. may be good for a slim fit.
