Kate Spade elegant black maxi dress, sleeveless, tie neck CO21

Black maxi dress Sleeveless The back zips up midway, closes with a hook and eye, then there is a pretty keyhole opening until the next hook and eye and also a button. The strings tie on top and flow down the back. Very pretty! A little wrinkled (see pics) but a steamer will get that out! Does not show size on the tag but it fit when I was a size 2-4. Very flattering. Questions and offers welcome!
