There can be no mention of London shopping without a mention of the Topshop flagship store by Oxford Circus. Whatever your opinion of the high street brand, their three-storey megastore is more like a small city than a shopping outlet, with tattooing, wig-fitting, art college showcases, vintage, print-your-own-pattern facilities, and of course the brand's own items. There's nothing you can't find, and if you can stomach the crowds, you might find yourself with an armload extra in luggage space to bring back with you. We recommend starting off on the basement level and working your way up to accessories, where you can get a cupcake and a cold pressed juice to fuel your day.
