In the 360 days since Prince William and Catherine Middleton exchanged vows and the world sounded a collective "awwww," we've followed the new Duchess very closely to watch how she develops her style. And we’re not the only ones—entire blogs are dedicated to her every fashion move. So, when InStyle.com wanted to find out which one look you liked best this year, we turned to the Kate experts behind What Kate Wore (Susan E. Kelley), Kate Middleton Style (Carly Wood), Kate’s Wardrobe (Sarah Tolan), and Duchess Kate Blog (Charlotte Crawley) to help us narrow down the choices. The result: The four looks above. Click through the gallery to find out why these became finalists, then help us pick her Best Look of the Year by voting for your favorite in the poll below. We’ll reveal the winning outfit next Monday, April 30th—the day after the First Royal Anniversary. So get voting!
