Ivory Peacoat - Banana Republic

I loved this peacoat but it's just not my style anymore - It's been in my closet for years. It is warm and comfortable and looks great on! It was dry cleaned before getting put away, but over the years spots have come up that were not apparent before - I think they can be spot treated. There is a button with a chip but it is not noticeable when wearing. See photos for fabric content.
