Black Full Length Express Sleeveless Dress

I've had this dress for a very long time, but it is very long on me and I have only worn it once for a performance, safety pinned. It has a racer-back and kind of sits like a halter-top. It has a silky-feeling lining that does not go to the end of the dress (see pictures). Measurements: Pit-to-pit: 15 in Waist band (stretches): 11.5 in Length (top of shoulder to bottom): 56 in It is in great condition and is very soft.
