Lace-Up Long Glitter Prom Dress: Aerie Couture 201No one will soon forget this long a line glitter prom dress 201 from Aerie Couture. In misses and some plus sizes, this gorgeous long evening gown is crafted in glittery fabric from the plunging v neckline to the hem for a dazzling look at prom, galas, and other black tie events. The long glitter formal dress has thin shoulder straps that lead to the lace up open back, while the long a line skirt opens in a side slit before pooling into a small train.
