Take Zimmermann's indulgent designs into the new season by opting for the Zippy maxi dress. The billowy design has been crafted from a diaphanous blend of linen and silk, and features a high-neck collar and belted waistline before falling into a full-bodied, floor-length skirt to create a figure-flattering silhouette. Let its distinctively '70s feel work as a retro-glam kaftan, taking cues from the SS19 runway.
