When she's designing pieces, Rosie Assoulin enjoys walking the line between what you're dying to wear and what has unique and unexpected details. First seen at the label's Spring '18 presentation, this crepe 'Cry Baby' gown has teardrop cutouts along the bodice and an open back kept securely in place with knotted ties. The voluminous silhouette is enhanced by fitted cuffs and a floor-skimming skirt - leave a few buttons undone at the hem for movement.
