The Ukrainian actress looked gorgeous wearing an Emilio Pucci Fall 2012 gown with a beaded neckline.
Not many could successfully pull off a sexy gown with a keyhole details and central slit, but Olga does with great aplomb.
Her sultry look was styled with neutral makeup, a simple bun, a black box clutch and matching pumps.
You may remember that Janet Jackson wore the same gown in white during Cannes Film Festival, but without the same success as Olga.
