It would be easier to compile a list of who doesn't shop there. Topshop's latest convert is Gwyneth Paltrow, who recently persuaded the store to open out of hours to rummage through the rails undisturbed. She stocked up on tops, trousers and a collection of beanie hats. She is obviously taking the indie-chick, celebrity-girlfriend look to heart - she wore one of the low-key £10 hats to watch boyfriend Chris Martin play at the Brits. At the recent London Fashion Week, foreign fashionistas made the huge Oxford Circus store their first stop and the high street store has managed to become as cool as the designers it copies. Celebrity customers: Gwyneth Paltrow, Kate Moss, Holly Valance, Cat Deeley, Britney Spears, Beyonce Knowles.
