The label Twenty8Twelve was launched in 2006 by Savannah and Sienna Miller. Sienna Miller knows the importance of being stylish and comfortable every day as a modern style icon and much photographed celebrity. She is the inspiration and creative muse of the label and its name comes from Sienna’s Birthday being the 28th of December. Savannah Miller began her love of fashion as a child of eight years old. She later graduated from London’s famous Central Saint Martins with a first class honors degree and went on to work for some of Britain’s finest designers: Alexander McQueen, Mathew Williamson, Anya Hindmarch and Betty Jackson.

The clothing is a reflection of the two sisters: a mix of glamour, punk, boho and rock chic. The clothing are wearable in a London chic way, with plenty of denim, cropped jackets, and rock chick style translated into today's modern woman. Super-stylish and super-wearable, the Miller sisters have proved that celebrities can design beautiful clothes.
