Emma Stone wore a Giambattista Valli Spring 2012 Couture gown to the Oscars.
While I like the dark raspberry colour of it, the high bow makes the dress resemble the Balenciaga gown that Nicole Kidman wore to the 2007 Oscars.
Emma's Louis Vuitton jewels were fabulous though, and despite the close resemblance to another dress, she looks great in this solid colour gown.
