What do Kate Middleton and Kate Moss have in common? According to this week's Twinning episode, these two share the same style once in while; they're recently spotted in the same classic two-piece ensemble. The Duchess of Cambridge rocks a Gucci look by day while the supermodel shares the (almost too similar) outfit during a night out. See who wears it better as these two British queens (style and royal) battle it out for the world's best dressed title!
