Very nice shirt of some vintage, probably not any newer than the 70's and might go back as far as they made this style. Lightweight woven fabric for summer or tropical wear. Chest around 40" at the armpits but most if it is 38" so this is a Medium. Sleeves 19" from the armpits and 23" from the top of the shoulder. Name "Ricardo" stenciled inside colllar. Likely cotton.

All we do to package these is wrap them in brown paper or similar, they don't get hurt and it saves you on the postage wherever you live.
