Vintage mid-century wool fully lined coat ILGWU size S-M

This was my step-grandmother’s beautiful coat. She was born in the 30s near Philadelphia so assuming this is from the 50s-60s. It is in pristine condition with intact buttons, fur in great shape and full lining, but definitely smells a little musty. I wish I could wear it but I’m an XS and it’s too big for me. Listing as a medium but it feels to me between a small and a medium. Made by International Ladies Garment Workers Union P to p 21” Length 39” Sleeve length 23”
