Black evening bag with silver chain straps

Super cute black, pleated evening bag with silver chain straps and silver closure. Perfect size(6.25 x 12.5 x 1.5). Not sure of the maker. A few spots noted in photos(last 2 closeups) where it has been rubbed, but as you can see from the first 2 pics, you can't see them at all. They are closer to the top. I think it may have happened when being stored.
