Here's a La Femme prom ball gown with a flair for sophistication. The sparkling beaded bodice of this open-back prom dress features a wide v-neckline and thin spaghetti straps. Tulle on this a-line prom dress forms a wide band of ruched fabric around the waist, flows to the floor in a poofy ball-gown style, and parts in a high side slit. For a classic look with a modern twist, wear this v-neck prom dress by La Femme.
