This is an Enisys cardigan. The bottom button is missing, but it's a very cute button. However, it's difficult to reattach, so I think it's fine to wear it buttoned only at the top, or not at all. I personally don't think it's much of an issue (^^) The size is 2, which I think is about a Medium. I've included photos of the flat measurements. There are no noticeable stains. Please understand that this is a used item before purchasing.
