With the fashion world at her fingertips, mom-to-be Kate Middleton (who's due in July!) has the wardrobe every girl dreams about. As of late, the gorgeous Duchess of Cambridge, who recently celebrated her 31st birthday, has been spotted wearing the season's color of the moment: burgundy. Spotted on the runways of Alexander Wang, Tibi, and Alexander McQueen, the rich hue has been integrated into Kate's wardrobe in a variety of chic ways. Whether it's a pretty silk long-sleeved dress from her latest appearance at the National Portrait Gallery in London (pictured at right) or her oxblood-hued Paule Ka skirt suit, it's safe to say Kate has mastered the popular color trend effortlessly.
