Ever since Kate Middleton became engaged to Prince William in November 2010, she hasn't been off our style radar. In the early days, her outfit choices were often safe and conservative. But, after wearing a Sarah Burton for Alexander McQueen wedding dress in April 2011, we've been seeing lots more of her elegant yet edgy side! The Duchess of Cambridge flies the flag for British fashion wherever she goes. Self-styled, she has a natural ability to mix high street favourites (Zara, LK Bennett, Whistles, Reiss) with fashion-forward high-end pieces (Alice Temperly, Issa, more McQueen!) flawlessly. We think it's in the Middleton family genes - just like the trademark glossy hair and gorgeous skin. Her younger sister, Pippa Middleton has also become one of the world's most closely watched women since the Royal Wedding. Last year alone, 'The Kate Effect' (that buying frenzy that takes place as soon as she leaves the house) apparently contributed £1billion to the British economy. She may be a Princess for a while yet, but when it comes to fashion, Kate's Britain's Queen.
