Jacqueline Ferrar Leather Jacket-Size Small (possibly)

Im not sure where to find the size on the jacket SO I went to other posts to see what the measurements are on others. I feel like this jacket is a small based on the measurements. Pit to pit is 22 Length is 29 Sleeve from pit to end is 17.5 Please make sure you look through the pictures well. Overall this coat is in excellent condition HOWEVER there is a small tear at front bottom. Its hidden by the last button cover but it's there nonetheless.
