Out of all the Bridesmaids stars at the Oscars, Rose Byrne wins the award for best dressed. The actress told E!'s Ryan Seacrest that this slinky sequin midnight-blue Vivienne Westwood one-shoulder gown was "the first thing [she] tried on," and she went with it. The fab accessories, including her sassy bob, stunning Chanel drop earrings and Jimmy Choo platform stilettos, don't hurt either. Way to go with your gut, babe!
