Oof! I love these shirts! I have a few and call them my Space Farmer shirts, like one of those 70s sci-fi movies where the farmers have futuristic clothes but like plaid and denim. Wear over tight jeans with a little gold stretchy belt over it, or un belted with short shorts. This is a style meant to be worn a little big so due to shoulder and neck measurements I’d say a medium- large.
