Black and gray wool pea coat

Beautiful charcoal and light gray pea coat size extra small. However, I would wear a medium in this does fit me, the length and shoulders are wide enough. So it would be bigger on someone that would typically wear an extra small, but probably good with layers very thick and heavy. Has interior pockets and buttons. Sleeves are 23 inches long, full coat is about 32 inches long. Shoulder to shoulder about 18 inches wide. About 21 inches across if the jacket is just hanging.
