In soft pastel, this long jersey prom dress is sweetly feminine with curve-hugging allure. From the designers at La Femme, this lovely long formal dress smooths over the shape from the draped v-neckline to the hem of the floor-length skirt. Thin shoulder straps cross over the open back of this fabulous evening gown before lacing up and tying into a trendy adjustable corset detail. Side ruching and a thigh-high side slit add a sexy vibe to this long designer dress. Delightfully stylish, this long pastel prom dress, by La Femme, is a great choice for prom, a military ball, or another formal event.
