At the opening of the Marrakech International Film Festival last week, the Basic Instinct actress (and event’s guest of honor) donned a floor-length dress with a flappy cleavage cutout paired with a beaded shiny cape that made her look ready to spew out spells at a moment’s notice. She even received a tribute that evening, presented by Martin Scorsese. Though her outfit was unexpected (does excess cape fabric cancel out her underboob display?), Stone looked absolutely jubilant. It might have to do with the fun fact that her keyhole cutout actually looked like a keyhole.
