Sienna brought a shot of eclecticism that we know and love to the Elle Style Awards. Sienna took home the style icon award and it's obvious why. She was a shining example of youth and funk in her Matthew Williamson printed and ruffled frock and feathered-shoulder Louis Vuitton tuxedo jacket. A few pieces of gold jewelry added more personal touches, and her designer buddy, Williamson, was the perfect arm candy. Congrats, Sienna!
