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 an easy-fitting shirtdress with pleat details along the bodice and a roomy fit through the sleeves. Throw it on with loafers or sneakers or go full-on French girl with a pair of ankle boots.
