For the spring collection of Isabel Marant’s Étoile line, the designer worked her trademark volumes into a fashionable lineup that melded seduction with comfort. Amped-up shoulders added heft — on a feminine, embroidered peasant blouse or gray acid washed jean jackets and vests. There were a lot of one-piece looks, including a vest-shorts combo in a faded tie-dye print, a long trouser jumpsuit in a western-inspired floral pattern and a dark boiler suit, cinched at the ankle, with ample volumes on the shoulders and arms. Fluidity came in the form of airy blouses and flower-printed dresses in silk chiffon while structured numbers included a double-breasted flannel suit and quilted jackets. In the footwear department, choices included ivory cowboy boots or studded white wide-leg heels.
