Xscape Floor length formal dress

Floor length trumpet gown. Strapless. Slit up the leg to about mid thigh. Ruffle on top edge. Only wore once to a Fireman’s Gala. *has a small mark on lower back - I did not take it to the dry cleaners yet because I only just noticed it as I took it out of the bag*. Has been stored in a plastic garment bag since the day I bought it.
