Formal, long sleeve, side split, V-neck, New Year’s Eve or gala event gown

Never worn, full length, black sparkly gown with long, sheer sleeves, and V-neck. Lightweight and fully lined. I ordered it and had it hemmed then realized it’s slightly large. It’s quite nice and comfortable. I’m usually a size 6:8 or US 10 and am 5’3”. For measurements message me.
