The Duchess of Cambridge has eclipsed fashion royalty like Alexa Chung and Kate Middleton to top the annual Harper's Bazaar Best Dressed list.

The fashion magazine's features director, Clare Coulson, said: "There wasn’t really any question in our minds here about who was our number one.

"The Duchess of Cambridge gave us the fashion moment of the year if not the century with that amazing wedding dress. But it’s also been so incredible to watch her develop in her role and I am sure it will be equally riveting watching her going forward."

As well as that stunning McQueen wedding gown, Kate is also famous for her elegant street style. Most of her high street outfits sell out within days of being identified.
