Vintage Forstmann Black Jacket/Blazer

This jacket is so stinking cute! It’s in excellent condition however there is a small hole under the right armpit that could easily be sewn up. Measurements taken with jacket laying flat: waist is 13”, from shoulder to hem is 18.5”, armpit to armpit 17”, sleeve length is 21.5”. There is no size listed but I it’s an XS.
