Forget the necklace, the Clarisse 2601 Prom Dress has got you covered. This slim fitting gown features a necklace of square cut clear gems built right into the plunging neckline forming a keyhole in the center. Loosely fitted, the skirt is belted at the waist with sheer accents and falls to floor length with a sweep train. A bold open back is a beautiful finish. Sizes 00 to 14.
