Cut on the bias to create a luxuriously languid shape, Lanvin's Inside-Out Gown is an effortlessly elegant way to channel this season's New Proportions trend. In midnight blue satin, the dress sees a panelled construction expose its seams, almost as if it were inside-out. Finished with an asymmetric hem, add leg-elongating heels and a classic clutch to complete a contemporary evening look.
