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. This is one of their famously soft, famously warm coats, made up in 100% wool. The cut hits right at your knee, so it'll look fantastic with tall boots.
