Style maven Sienna Miller took a swing at something new with this blazing 3/4 sleeve Jonathan Saunders cocktail dress and it was, unfortunately, a swing and a miss. If the fiery lookin' frock was simply gold and black, she may have pulled it off. Sometimes the British fashion plate sets trends, and other times just strikes out. No matter what, though, Sienna is stunning and we adore her fashion risks. (Photo: WENN)
