Sleek and sexy, this long prom dress has strategically placed cut outs that are as eye catching as they are impressive. Great for prom, military balls, and other fancy formal events, this floor-length evening gown includes sheer shoulder straps that lead to the open back. From La Femme, this long designer dress smooths over the hips before opening in a side slit and flowing down to the floor. A great find for the budget-minded fashionista, this close-fitting long prom dress by La Femme is as bold as it is figure flattering.
