Zimmermann's Castile top comes from the label's Summer Swim 2018 collection, and we think it should be the first thing you pack for your next warm-weather vacation. It's crafted from light and airy cotton crochet in a milky ivory shade and is defined by a voluminous ruffled trim. The shoestring waist tie cinches the silhouette, creating a figure-flattering peplum. We love the fluted cuffs for a fashion-directional finishing touch.
