Brooks Brother Trench Coat - New without tag

Up for sale is a brand new trench coat for women, cream/beige color. It's in brand new condition without tag. It has never been worn before. Unfortunately, the tag was lost sometime when we moved from a house to a condo. Honestly, I don't know how much I should ask so please send me your offer. I would be happy to consider. Also, please let me know if you have any questions.
