2011 has been a momentous year for Kate, seeing her wed in one of the most eagerly anticpated weddings for some years. She has also come into her own, attending high profile event appearances and her successful tour of North America with new husband William, Duke of Cambridge.
Kate has become famous for her simple, elegant style, favouring a well-balanced mix of high end and high street fashion names to make up her often recycled outfits and wardrobe.
Though some have criticised the newest addition to the royal family for her safe fashion choices, usually consisting of pencil skirts, wrap around, knee-length dresses, LK Bennett court pumps and clutch bags, it is her attitude to style and fashion that has made her a popular fashion icon with people all over the world.
Nearly two billion people tuned in to watch her walk down the aisle in her customed designed Sarah Burton creation and since then, the world has not stopped taking note of the Duchesses next outfit choice, where it's from or who it's by.
Harper's Bazaar have said that there 'wasn't really any question in out minds here about who was number one', and said that the 'Duchess of Cambridge gave us the fashion moment of the year if not the century with that amazing wedding dress'.
The popular fashion magazine awarded second place to Florence Welch, followed by Andrea Riseborough and model and 2011 bride Kate Moss. Alexa Chung was placed ninth.
