Look to Rochas for opulent eveningwear with a distinctly feminine flair, such as this black velvet-devoré midi dress, first unveiled on the AW18 runway. It's made in Italy for a slim fit with a flattering V-neckline and an artfully nipped-in waist, then falls into a sweeping skirt comprised of gathered olive-green and black velvet panels. Ground the diaphanous silhouette with block heels.
