Isabel Marant personally tries on each of her designs to ensure that even the smallest details are perfect. From the designer's Étoile line, this 'Lemony' top is cut from cotton-poplin in a figure-skimming silhouette defined by ruching along the voluminous shoulder. It's trimmed with a flouncy floral-print ruffle that falls along the three-quarter length sleeve. Tuck yours into a slim skirt.
