Beloved for her relatability, famous for being a decidedly unfamous sort of star, Sandra Bullock is pretty much the definition of the cool girl next door. Yet as naturally funny and, we daresay, congenial as many of her characters may be, she turns up the heat on the red carpet with distinctive glamour. Whether Bullock is stunning in a beaded, fairy-tale Marchesa dress to accept the Oscar in 2010 for The Blind Side or sleek in a form-fitting Alexander McQueen, her big-night choices are all the more elegant for their contrast to her real-world self. So the fact that the utterly down-to-earth actress skyrockets to outer space in the upcoming thriller Gravity comes as little surprise to her devoted following. Here, our favorites of Sandra Bullock's red-carpet looks.
