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 shaker-stitched pullover is a quintessential Marant layering staple — made up in soft baby alpaca yarn. It's finished with almost-open sides, which makes it especially easy to throw over a tee or pretty patterned blouse.
