I’m distinguishing this one from Sam’s Green Two-Snap Coat with the word “Panel” because there are way more seams on this coat than there necessarily have to be. It seems to be made up of different sized panels stitched together. The two breast pockets do up with one snap that is mostly invisible. The breast pockets have two seams running down their middle, and there are two horizontal seams in the jacket midway between the pockets and the bottom. It does up with a zipper.
Brand Information: Possibly a custom replica of a Guess brand jacket.
