Sienna and Savannah Miller debuted the Spring 2011 collection for their label Twenty8Twelve Saturday night in central London. The clothes, which were inspired by Joni Mitchell's "Don Juan's Reckless Daughter" and Jack Kerouac's On the Road, featured dresses and skirts with feminine details and cool denim separates for day and slinky silhouettes for night. Miller's beau Jude Law sat front row for the show with designer and friend Matthew Williamson. "I'm here because I love Sienna Miller," Law, clad in a classic gray Alexander McQueen suit and signature porkpie hat, told WWD.
