>> Sienna Miller says her sister Savannah is hard at work on a new clothing label, which is her first foray into the fashion business since both siblings left Twenty8Twelve late last January.
"My sister is an amazing designer — she's working on her new label at the moment," Sienna told Vogue UK. "In fact she's designing in my attic as we speak. I just can't wait to wear all of the pieces."
While Sienna didn't say what any of those pieces would look like, Savannah's established aesthetic speaks to a very British sensibility — influenced no doubt by working for other British design talents like Alexander McQueen, Anya Hindmarch, and Matthew Williamson.
The Millers started Twenty8Twelve as co-creative directors in 2007. They left the brand in early January 2012, shortly before they were scheduled to present their Fall 2012 line during London Fashion Week. Sienna, who is currently pregnant, told WWD that she and her sister were "looking forward to new pastures. We wish the brand the best of luck for the future."
Twenty8Twelve has continued as a brand without the sisters' involvement, changing its full name from Twenty8Twelve by s. miller to Twenty8Twelve London.
