Port AuthorityMen's Retro Camp Shirt

I have a long torso, do the shirts run long or short?

What color is the back of the shirt?

I'm 5'6" 225lbs...i usually wear a x large in this style...should i get the x large?

I usually wear a size medium in women's shirts. my bbq team is ordering this and i was wondering what size i should get. any suggestions? thanks
