Ivory Gown With Jeweled Neckline And Black Cape Sleeves Plus Size 2 2X 18/20.  This is a Torrid prototype, but it looks like it was never put into production. I think it may be a fandom costume because it says "All wicked All the time" on the inside back.  It is a quality gown with a nylon lining inside.  The sheer cape sleeves are very striking!!!
