U.S. Michelle Obama, France's Carla Bruni-Sarkozy and the United Kingdom's Samantha Cameron are all on the top.

"Michelle Obama plays a very important role in fashion right now," Amy Fine Collins, Vanity Fair special correspondent said, "Carla Bruni-Sarkozy has a sexier, sultrier look. And Samantha Cameron is the first visibly pregnant first lady we’ve had on the list."
