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 Christa Top is made up in their soft, go-to cotton voile with delicate frills along the shoulders and neckline. It's finished with a pretty mock neck and a full-button placket.
