Do you know the designer that is dominating Princess style in Europe this year? Let me tell you. After years of Armani, Chanel and Dior leading the way for any good royal, this year Elie Saab has snatched the desirable crown and is reveling in Queen Bee role. The latest (and prettiest) of all the royals to wear Elie Saab is Charlotte Casiraghi, Princess of Monaco, sister in law of our own Charlene.

Stunning in grey silk, she attended the Art of Cartier exhibition in Madrid a couple of weeks ago. Beautiful, right?
