DANGEDIYA Wool/Cashmere Long Coat - New without tag

Up for sale is a brand new wool/cashmere long coat, Black color. I compared with my coat and believe the size is M/L. My friend gave it to me as a gift. It's in brand new condition without tag. It has never been worn before because it doesn't fit me well. Unfortunately, the tag was lost sometime when we moved from a house to a condo. Honestly, I don't know this brand although it's in very high quality and therefore 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.
