"I admire Jeanne Lanvin's uncluttered style, " says Creative Director Bouchra Jarrar, "enhancing the woman without erasing her personality." This dress shows how she has taken this approach and translated it for the modern day. Cut from black crepe, it has a short V-neck and knots at the front to create the illusion of a slimmer waist. Wear it with a jacket over your shoulders for work, adding earrings and heels after hours.
