By now, you’re probably well aware that the Duchess of Cambridge turns 31 today (we get a little excited about her here!), and we couldn’t let the day pass without talking about her amazing sense of style. Kate always looks great — even before she became a Duchess she was dressing well — but with her first year of marriage down and a big baby announcement, we think 2012 was truly her best fashion year yet. From the sexy gowns she wore in London in early 2012 and the casual frocks she chose for the Olympics, to the oh-so-appropriate dresses she donned in Asia and the stunning gown she wore last month, she really knocked it out of the park. And we noticed. So in honor of the Duchess’s big day, check out our gallery of her 31 best looks of last year. Tell us: Which of Kate’s recent dresses was your favorite?
