Jessica Chastain may be fairly new to the Academy Awards scene, but when it comes to her fashion on Oscars night, she's totally old school. The "Zero Dark Thirty" nominee dazzled on the red carpet in a gold strapless Armani Prive dress that she said was, “very old Hollywood." "It's a very happy birthday Mr. President kind of dress,” she told E! on the red carpet. Also old Hollywood: her reported feud with fellow nominee Jennifer Lawrence. The two were reportedly being kept far apart during the show.
