Here's an impressive long a-line prom dress that sparkles with every move you make. The embroidered-lace evening gown features crystal beading on floral appliques that offer a dazzling look at prom, fancy galas, and other formal events. From Ellie Wilde, this long designer dress has sparkly thin shoulder straps that lead to the deep v-back, and a fully-lined long a-line skirt with a crystal-embroidered tulle overlay that opens in a side slit before flowing to the floor in a shimmering a-line shape. Leave the purse at home because this long a-line prom dress has side pockets that allow you to keep your valuables safely by your side.
