The royals have arrived! Well, not those royals… While Prince William and Kate Middleton are occupied with the French state visit, Sienna Miller and her partner, Oli Green, enjoyed Wimbledon from the Royal Box.

Miller riffed on tennis whites in a romantic Alessandra Rich dress printed with purple and orange roses. While the body-hugging mini dress could have leaned sexy, its volant collar with a black bow, puff sleeves, and ruffle at the hip gave the look a more pastoral feel. Accessorizing her sweet, summery dress, Miller added a large Bottega Veneta tote bag in the brand’s signature intrecciato leather and a pair of oversized sunglasses.

Green dressed the part of a Royal Box attendee, in a navy suit, gray tie, and thick black Ray-Ban Wayfarers, matching Miller’s frames.

In years past, Miller has run the gamut of Wimbledon outfits, from the flowing two-piece polka-dot set she wore last year to the cinched-waist pinstripe Ralph Lauren number she paired with towering platforms the year before. But in her white floral dress, Sienna Miller raises the perfect courtside look and the perfect summer dress.
