Managing director of the IMF Christine Lagarde is widely regarded as one of the most powerful women in the world, and now she's been named one of the most stylish.

Ranked among style stars like Michelle Obama , Carla Bruni and the Duchess of Cambridge, Lagarde has been named to this year's Vanity Fair Best-Dressed List .

A frequent wearer of Chanel and other French designers, Lagarde's style is fresh, fashion-forward and, above all, professional. Among our favorite outfits are the American flag printed scarf she wore after the 2008 election and a sea foam-gray Chanel gown at the Qatar State Dinner...not to mention her leather biking gloves.

Check out some of her best looks below and tell us what you think.
