Yesterday Rooney Mara attended her sister Kate‘s premiere of a new Netflix series called House Of Cards, and the actress kept it pretty low-key, donning a black jumpsuit while her sis wore Dolce & Gabbana. But last night Rooney hit the red carpet for the New York premiere of her movie Side Effects, and she looked absolutely stunning. This cream-colored Alexander McQueen dress looks like a friggen wedding cake on Rooney– I love it! And I can’t wait to see Side Effects! We saw the trailer a while back and it looked pretty awesome. Peep the gallery for more!
