La Perla's robe mixes the elegance of lingerie with the sharpness of suiting. Made from featherweight stretch-silk chiffon, this piece is layered with a neoprene waistcoat and has a floor-skimming skirt with a thigh-high slit at the front. It's too good to be kept hidden at home, so try layering yours over a pair of leggings for evening events.
