1. Victoria Beckham

Many people scoffed when Victoria announced that she was moving into design, but she has proved her doubters wrong. Unlike many designers, she produces simple, flattering dresses, and after several collections her reputation is well established.

2. Nicole Ritchie

If your taste runs more to hippy chic than the tailored Beckham dresses, then Nicole Ritchie’s House of Harlow may be more your style. The former BFF of Paris Hilton has turned her attention from partying to working hard, and her hippy print dresses have been well received.

3. Sienna and Savannah Miller

While I don’t rate Sienna Miller much as an actress, her venture into clothing design has a sound background. Sister Savannah is a trained designer, and together the two launched twenty8twelve. The range is now stocked across the world.
