Natalia Vodianova looks smashing standing alongside her hubby, Justin Portman, at the ARK dinner gala in London. Notice how the model's unique one shoulder cutout dress is simultaneously sexy and sophisticated. I like how she adorned herself with standout multicolor baubles for a funky pop and slick Givenchy open toe booties for major sass factor. Don't they make a hot power couple? Sizzle . . .
