The fabulous long designer dress is crafted in soft jersey from the v-neckline to the hem of the floor-length skirt for a fitted look at prom, black-tie weddings, and other formal events. A front knot twist detail at the waist adds interest to this slinky evening gown, while thin adjustable shoulder straps cross over the open back for a flirty look. Simply lovely, this long La Femme prom dress is as versatile as it is beautiful.
