Purple-sequined “Olivie” is a glimmering, provocative delight for a multitude of black-tie affairs. All eyes will be on the woman who crosses a room in this dress, which drapes so flatteringly in silk charmeuse and allows you to move with confidence and comfort. A jaw-dropping deep V-cut makes the front not only glitzy, but daring; wide cross straps and a peek of back and shoulders add interest from behind. A slim pencil skirt falls to just above the knee, and this dress closes with a zipper at the center back.
