She is a queen of cool....
Emmanuelle Alt - the editor-in-chief of Vogue Paris since February 2011, succeeding Carine Roitfeld. She's one of my style icons and she does denim and anything casual with such upscale, effortless sophistication that it makes me cry sometimes.
She is also well-known for rocking a peacoat - it's one of the four standard coats that every woman should own. If you're looking for your own version of reasonably-priced, laidback cool check out H&M ($79), J.Crew ($298) and ASOS ($303).
