Topshop is the ‘It’-store when it comes to high-street shopping. Encapsulating London’s supreme skill at bringing catwalk fashion to the youth market affordably and quickly, it constantly innovates by working with young designers and celebrities. It’s the store that famously runs the popular Kate Moss collection. It has an entire floor dedicated to accessories (hair clips, tights, sunglasses, you name it). And if the store’s five floors intimidate you, you can book an appointment with a personal shopper.
