  • Description
  • The Onyx Midi Dress is all about what happens between 12am to 4am. Featuring a high neckline with a keyhole opening that turns to reveal an open back, the criss-cross sequin mesh and the feather trimmed 3/4 sleeves are details that one cannot miss as your flounce your way through the night. Designed with a fitted bodysuit lining and a zip fastening at the back skirt, we suggest downsizing as fabric holds stretch.
