A favorite this season, this long a-line prom dress is a classic style with, yes, pockets! In gleaming fabric from the scoop neckline to the hem, this beautiful long formal dress has thin shoulder straps that create a statement as they lace up over the open back. A thin rhinestone belt adds a bit of sparkle to this gorgeous evening gown, while the long skirt flows to the floor in an a-line shape. Affordably priced under $200, this long a-line prom dress is offered in misses and some plus sizes.
