A side-twist cut-out detail makes this long prom dress a chic design for the girl who loves a daring look. From La Femme, this long designer dress smooths over the curves from the surplice v-neckline to the floor for a shape-enhancing look for prom, galas, and military balls. Side cut outs and a twisted design on the hip of this fabulous v-neck evening gown offers a sexy vibe, while the thigh-high slit adds to the look. Thin shoulder straps create a corset design as they lace up over the open back of this long formal dress. Heads will turn when you make your way through the doors in this gorgeous long prom dress from the designers at La Femme.
