British department store John Lewis tapped Alice Temperley to create a more affordable range, called Somerset by Temperley. "I wanted it to be very much a collection of essentials," the designer told The Telegraph. Shoppers can expect to see "feminine and functional" looks, like the ones loved by the Temperley's celebrity clients Catherine, Duchess of Cambridge and Heidi Klum. The 60-piece line will launch September 4th, with partywear expected in October. And while there aren't any John Lewis outposts in the US, the store does ship stateside.
