Vintage Navy & Pinstripe Liner Reversible Coat Shorter Sleeves Stylish Warm Rare

honestly cannot find another like this anywhere. I am unsure of size all I see is a P and not sure what it means. I am 5'11 160 pounds and I am in photos. the arm length is short for a reason as it will not reach your wrists, its awesome for fall or winter if you run hot. its 65 percent cotton 35 percent polyester. all around extremely rare vintage coat. New York Yankees colors. also has a bit of shoulder padding which makes me think this may be women's or unisex. but not sure how to tell, I've worn it before and got compliments and I'm a straight male.
