She's a Duchess. Does someone of her social stature play by a different set of fashion rules? And she's married to a man 25 years her junior. Maybe she dresses younger for him? But a bikini at 86?

She's the Duchess of Alba, and she's rocking a floral print bikini on the Mediterranean island of Formentera on vacation with her much younger husband, Alfonso Diez. The Duchess is well known for her whacky, fun sense of style but how old is to old for a bikini? See her on the beach here and here!

Share your thoughts with us! Is a more modest bathing suit in order, or is she rocking the two piece just fine?
