Ever since Catherine, Duchess of Cambridge, walked down the aisle in a breathtaking Alexander McQueen by Sarah Burton wedding gown in 2011, she not only became British royalty but also a fashion princess.

This year, with the Queen’s Diamond Jubilee and the London Olympics, Catherine only cemented her status as the best-dressed royal, where she set trends, inspired styles, and caused more than a few designer items to sell out within hours.

Her personal style—prim, proper and uncompromisingly classic—may not be as adventurous and daring as some other best-dressed winners, but she still manages to make a dazzling spectacle with her trendsetting (and sometimes repeat) staples.

Her favorite designers include Erdem, Jenny Packham, Katherine Hooker, LK Bennett and McQueen, natch. But what makes Catherine so charming is that she wears High Street style from Reiss and Zara just as royally.

Now that she’s pregnant, rest assured Kate will have the most well-dressed baby bump of 2013.
