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. Like the Plalia top — a quintessential IM silhouette with pin tucking at the yoke and an easy, billowy fit through the body and sleeves.
