Started in 2006 by actress and style icon Sienna Miller and her sister Savannah, Twenty8twelve, named after Sienna’s birthday, fuses romantic Boho style, a pinch of French chic, and a touch of biker with everything sexy, young, girly, and cool. Sienna stands behind the brand’s inspiration, while Savannah, a Central Saint Martins grad with stints at Alexander McQueen and Matthew Williamson, heads up design.

The full range collection spans from figure-hugging jeans and wide-legged trousers to pussy bow blouses, sequin-laden cashmere cardis and hot pants. Hilights incude printed T-shirts, which are designed in collaboration with a different artist every season.
