NWT With the belief that "when a woman smiles, her dress must smile with her," French couturier Madeline Vionnet created garments to accentuate a woman's natural shape - her most iconic design being the bias cut. This artful technique required the fabric to be cut at a 45-degree angle, allowing it to softly drape and curve in the most flattering of ways. Here, the classic silhouette transforms this silky slip dress into a feminine piece that feels au courant.
