This long high-low prom dress, by the designers at Alyce, is reasonably priced under $250 for formal events. The sleeveless evening gown, made from stretch taffeta, holds its shape and gives a comfortable fit. The crossover ruched v-neck bodice has multiple thin shoulder straps that continue over the open back in a unique design. Extending from the natural waist, the long a-line skirt ripples to a flirty short off-center hem and cascades to a romantic floor-length hem in back. For a striking entrance to prom or a head-turning look on a pageant stage, wear this long high-low taffeta prom dress by Alyce.
