We haven’t taken our eyes off her since Prince William proposed. Always polished and radiating a contagious smile she is the definition of poised. No surprise she tops Vanity Fair’s 2012 International Best-Dressed List.

Yahoo has all the details.

Ever since Prince William said he was marrying Kate Middleton, the world has been obsessed!

The media has helped to fuel the fan frenzy by documenting her every move — and every stylish outfit, from the iconic navy blue Issa dress she wore to announce her impending nuptials in November 2010, to her many colorful, elaborate fascinators, to the sleek Christopher Kane design she sported at the opening ceremonies of the London 2012 Olympics.

Not surprisingly, for the second year in a row, the Duchess of Cambridge tops Vanity Fair’s 2012 International Best-Dressed List, which also includes Middleton’s brother-in-law Prince Harry, as well as fashionable famous names like Jay-Z, Colin Firth, Alicia Keys, Diane Kruger, Tom Brady, and “The Help’s” Jessica Chastain.
