With the days of bohemian frocks, floppy hats, and slouchy ankle boots behind her, Sienna Miller is now all about protecting her refined edge. The British actress' Victoria Victoria Beckham dress, Prada shoes, Salvatore Ferragamo sunglasses, and Alexander McQueen handbag ensemble (above, right) is the perfect middle ground look that sums up her style. For a more glam look, Miller turned it up a notch as the 2015 Cannes Film Festival in Balenciaga (above, center) and then showed us how to master relaxed street style in a cream-colored Stella McCartney top paired with black trousers and suede mules (above, left).
