Banana Republic 100% Silk Black Dress Floorlength

Silk floor length black dress. Zipper up the back until your tail bone. No slits. Scoop neck. Flows out slightly wider at floor, so it's easy to walk in. I am 5'7" and it's perfect length to stay off floor and shoes if I put heels on. Low back but you can still wear and bra and it isn't seen. Very elegant and flattering for Silk. Says size 2, but can fit 4 and small size 6. The last picture shows the back.
