Wowsa! We told you disco and Dynasty was back – but we don't think we'd be quite as brave as Sienna Miller was by wearing this new season Gucci sequin suit head to toe. We do like the way she kept her hair and make-up totally minimal to balance out the strong look, though. If it was up to us (because, you know, we do like to dream about having first dibs on straight-off-the-catwalk Gucci), we'd be more likely to wear the jacket or jeans separately. But then again, we don't have a movie to promote – or Channing Tatum as arm candy. What do you think of Sienna's latest catwalk-to-red-carpet creation?
