Since debuting at Paris Fashion Week, the Lafstee over-the-knee boots from Isabel Marant's Fall/Winter 2018 collection have been topping our wishlist. Crafted in Italy from velvety calf suede, the black style possesses cascading waterfall fringe along the sides that creates a moves-with-you silhouette. Wear yours with an oversized knit and borrowed-from-the-boys trousers to emulate the runway look.
