Bitch Stole My Look: Gwen Stefani vs. Iman

Yesterday, Gwen Stefani donned Stella McCartney's supersexy, chest-baring, sequin one-piece with sheer sleeves to the Tree of Life premiere at Cannes. The rocker paired it with a red clutch, hot-pink pout and curly 'do.

Just weeks earlier, supermodel Iman took the same plunge in a disco-tastic gold version at the Met Costume Institute Gala. A black clutch, smoky eyes and voluminous hair completed her look.

Which babe wears it better, dark-horse Gwen or golden-girl Iman?
