Never Worn. This Topshop jacket fits large!! I'm usually a size US14 and when i recieved this jacket it was 2-3 sizes too big and i couldnt return it. Therefore, this should fit you if youre usually a size US18. The pictures of me wearing the coat are the smaller size i have (US8) for a better idea of what it would look like on. The jacket has never been worn outside, and its still in a plastic covering.
