Emmy Rossum in Oscar de la Renta

Emmy Rossum attended the New York City screening of the new Disney movie Oz the Great and Powerfulstarring James Franco, Mila Kunis, Rachel Weisz and Michelle Williams.  The Shameless actress looked ready for spring in a floral fifties-inspired dress by Oscar de la Renta.  Rossum, who has a new album coming out this year (who could forget her moving performance as Christine in the hit musical movie The Phantom of the Opera), looked delightfully sweet in the short sleeve frock, which she paired with two toned green pumps.
