I have posted *shirt measurements* below your comments - for your reference, as well as anyone else who may want to know them. Thanks for your interest in my auction!
They both appear to be Men's, judging by the sleeve length, and overall size - but I believe they would just appear slightly larger on a woman. The tags do specify "Men's" or "Women", so I can only go off of how they appear.
Thank you for your bid, and sorry I did not specify those details in the auction listing!
