All of the many very stylish members of the British Royal Family (Princesses Beatrice and Eugenie and Kate Middleton included) have one thing in common: A penchant for fantastically imaginative hats.

Prince Charles' wife of seven years Camilla is no exception. The Duchess of Cornwall, formerly known as Camilla Parker Bowles, might even rival the younger royals when it comes to head gear. Since she married into the family in 2005 after divorcing her husband Andrew Parker Bowles, Camilla has stepped up her formal-wear. Always a conservative dresser, Camilla favors blue, purple and pastel-colored monochromatic outfits (which include matching bags, shoes and, yes, even hats).

To celebrate the Duchess of Cornwall's 65th birthday on Tuesday July 17th, we're taking a look back at some of her craziest hats and many suits over the year. What do you think of Camilla's style?
