Isabel Marant is practically synonymous with insouciant, Left-Bank-bohemian chic, and Étoile 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 Estelia top, an easy-fitting flowing tunic finished with IM's go-to lace detailing along the collar and placket. Simple and sophisticated.
