Victoria Beckham

This Spice Girl isn't 'too posh to push' the Beckham brand, which is now worth an estimated £112 million. Since her lucrative girl band days, she has reinvented herself as a style icon after topping more 'best dressed' lists than pop charts.

Her trademark DVB skinny jeans and over-sized sunglasses have boosted her Hollywood street cred. Recently, she dressed to impress in Cavalli on the Spice Girls' reunion tour and made another £10 million.
