Love It or Hate It: Sienna Miller in Matthew Williamson

Sienna Miller hosted a party last night for the launch of Matthew Williamson's book in London. The actress, who sat in the front row at his show last month, wore a blue maxi dress from his Spring '11 collection. Sienna wore no jewellery letting the dress do the talking. It's such a beautiful shade of blue, but do you like this dress on the actress?
