About Twenty8Twelve

Part 1920s, part rock 'n' roll, Twenty8Twelve designs clothing for women who express their love for culture and the arts through their sartorial choices. Actress Sienna Miller and her sister, designer Savannah Miller — born three years apart in New York and Hong Kong respectively — have always shared a passion for fashion, and launched Twenty8Twelve in 2007. Named after Sienna’s birthday (December 28), the Millers' London-based label blends casual and couture: think classic denim jackets paired with whimsical printed scarves in soft modal, faded jeans and jean shorts, soft trapeze dresses in sweet prints, and pleated skirts. With a celebrity following that includes Kate Bosworth and Keira Knightley, Twenty8Twelve is your fast track to Hollywood fashion.

Co-designers and sisters Sienna and Savannah Miller were born three years apart in New York and Hong Kong and have always shared a similar design sensibility. Sienna (an actress) and Savannah (designer), were approached by fashion entrepreneur Carlos Ortega in 2006 to develop Twenty8Twelve, their fashion line, named after Sienna’s birthday (December 24th). Part 1920’s, part rock ‘n’ roll, this collection has turned into international fashion must-haves. With distribution worldwide in top stores like Henri Bendel, Intermix, Saks Fifth Avenue and a flagship store in London as well as a celebrity following that includes Kate Bosworth and Keira Knightley, Twenty8Twelve is an exciting addition to Gilt Groupe.
