Super feminine, this strapless long prom dress by Amelia Couture is as figure-flattering as it is sparkly. With a sheer beaded corset that wraps around to the lace-up back, this strapless long formal dress has an oversized bow at the neckline for even more feminine appeal. The lace-up strapless long evening gown has a long skirt with tummy-camouflaging ruching, booty-contouring pleats, and a thigh-high side slit. The small train completes the look of this exciting strapless long prom dress that is surprisingly priced below $200.
