From La Femme, this long a-line prom dress 32028 is a classic style with plenty of modern details. With embroidered floral lace from the v-neckline to the skirt, this open-back long designer dress gets a sweetly feminine look, while the sheer corset-style waist brings on a flirty vibe. Matching embroidered lace flows onto the long a-line tulle skirt that opens in a side slit, while this long formal dress has thin shoulder straps that adjust before lacing up over the open back. Sweet and sassy for prom, galas, and other formal events, this long a-line prom dress is two styles in one beautiful package.
