Aureta for Anthropologie Amazing Dress

This is such a high quality black cocktail dress. Designed by Aureta for Anthropologie. Size is xs which is a bit too small for me, the only reason why I am selling it. The zipper in the back did not close due to the mannequin being too big. The fabric is cotton, I would say heavy cotton but still light when you wear it. The tag came off but I have it somewhere.
