J Peterman XS vintage black coat

J Peterman coat. Vintage. Long and double breasted. Front pockets. Armpit to armpit 19 1/2 inches. 45 inches long. Extra small. 100% silk. Tie adjustable sleeves. See picture. There’s one small area near the slit in the back. I’m not sure what it is. Maybe taken in some. But wanted to make the buyer aware.
