During her Oscar campaign for The Girl with the Dragon Tattoo, Rooney Mara became close with designer Riccardo Tisci, making their partnership as co-hosts for the Costume Institute a much anticipated affair. With her hosting duties comes certain responsibilities, including being one of the first celebrities to arrive. When she stepped onto the red carpet, Mara took our breath away. While her look only bordered on punk with slight accents like zipper detailing, it’s undeniable that her dress was certainly a beautiful Givenchy moment. Bold shoulders, a deep V front, and an open back provided the details for her white lace dress. To top it all off, she opted for a dark lipstick, zero accessories, and a slicked back hair style.
