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 Nelly is a very feminine, very chic take on a wool shirt-jacket, with a jewel-neck collar, patch pockets at the chest, and subtle puffs at the shoulders.
