Architect Zaha Hadid attended a summer garden party hosted by Burberry at the Serpentine Gallery in London yesterday, wearing a big black and sleeveless sculptural coat with a jagged geometric gold print. Under it she wore a simple long-sleeved strappy black blouse, black leggings, and black boots. (And she carried a black clutch too, to keep the color theme going strong.)

Though it's a great piece regardless, is this more of a coat, a shrug, or a poncho? And would it have worked better with another slightly contrasting color somewhere else in the look?
