sienna miller models twenty8twelve SS11 lookbook.jpg

When you are a super A-list starlet who has her own fashion label, why would you pay anyone else to front your label's Spring/Summer '11 lookbook? I am sure that is the thinking behind Sienna Miller's decision to model the latest collection from Twenty8Twelve. In addition to recently launching a pop-up shop, Sienna acts as house model appearing right at home in breezy summer dresses, casual printed shorts, and ruffled skirts.
