We’re especially excited about new pieces from Twenty8twelve, a clothing line by actress Sienna Miller and her sister, Savannah, who previously worked at Alexander McQueen and with Matthew Williamson. Our stylist has paired a twenty8twelve jacket ($455) and scarf ($98) with a yellow top by Nanette Lepore ($215); jeans by Marc by Marc Jacobs ($188) and black shoes from Kors by Michael Kors ($230).
