Isabel Marant is practically synonymous with insouciant, Left-Bank-bohemian chic, and Etoile is the younger and more wearable — but equally cool — sister of the main line. It's full of relaxed tops, romantic dresses, and plenty of Isabel's signature ruffles and lace.The Gabriel is one of IM's signature, wildly cozy coats made up in a beautifully checked wool. The cocoon shape is chic enough to throw on over a dress, and the material is soft enough to lounge around in on a Saturday at home. Win, win.
