Womens Arden B cocktail dress size 4

I loved this dress and unfortunately will not fit into it in my near future. It has a cut out back feature which was so cute. Comes with bellt, as photographed one of the belt loops is very worn. There is a slight dark stain on bottom of dress as also photographed which could come out in an additional wash or dry cleaning as I don’t like to overly wash my dresses. I haven’t worked in the stain because I don’t want to damage the dress.
