Carey Mulligan attended last night's annual Metropolitan Museum of Art’s Costume Institute Gala on the arm of her new husband, Marcus Mumford of the band Mumford & Sons. The British newlywed chose a glittering gold and silver paillette-covered dress by one of her favorite designers, Prada. Not only is the label one of two honored by the esteemed museum this year, she also wore a custom Prada gown for her wedding in the English countryside two weeks ago. The only thing that glittered brighter than her dress was her diamond engagement ring, which featured a blue diamond or sapphire gem on either side, and gold wedding band, shown here for the first time since the pair tied the knot.
