Victoria Beckham may be succeeding in conquering the world of high fashion. Following much speculation, it has been confirmed that the LA-based Spice Girl is to star in next season's Marc Jacobs campaign, shot by Juergen Teller. Also, her dVb sunglasses, left, are currently available to buy exclusively in Harrods. There are only 10 pairs available to buy in the UK (they are also available at other stores worldwide) and have the name of the store they were bought from etched on the inside of one of the arms.  Victoria has just added an acid wash in the skinny style to her jeans collection, going on sale exclusively at Harrods next week.
