From the designers at La Femme, this long prom dress is a real showstopper. In soft jersey fabric, this tight evening gown smooths over the curves for a sexy look at prom, fancy wedding receptions, and other formal events. A unique cowl v-neckline tops this curve-hugging formal dress, while thin shoulder straps lead to the deep v-back detail. Ruching at the torso and open back completes the alluring vibe of this long prom dress by La Femme.
