Toni Maticevski's sculptural designs are not only striking but flattering, too - his Pre-Fall '19 collection eschews unnecessary detail in favor of shape, fabric and texture. This 'Potion' dress is cut from smooth cady in a fitted one-shoulder silhouette and has a voluminous flouncy ruffle that drapes around the back. Unzip it slightly at the side to show a little more skin.
