Sienna Miller and big sis Savannah cozy up at a dinner supporting the Twenty8Twelve by S. Miller Spring 2010 collection in New York City’s Royalton Hotel Penthouse on Monday (November 9).
The 27-year-old actress spent her night off of the Broadway stage celebrating the collection with guests from Vogue, Marie Claire, Teen Vogue and Intermix.
“We were inspired by Willem de Koonig and Jackson Pollock and some of those crazy artists,” Sienna said in a Vogue video, “so with our prints, we really went out there.”
