Ashley B grey convertible fall/spring coat industrial punk vibes

I love this coat but it’s a bit too small in the shoulders for me. It has a really large collar that can be zipped up and folded or worn half over the face. It has four pockets, all with flap and snap closure. The bottom half of this coat is removable! It’s attached with a zipper. Once this panel is removed, the coat is around upper-butt length. There are some blemishes on this coat but not easily noticeable. There is a stain that is slightly darker than the coat’s color. It’s located in the front near where the zippers all meet. There are also some spots of what looks like bleach? One such spot is in the back left near the pit. Last few photos will show these blemishes. Brand: Ashley B Size: Unknown.
