Fully-sequined, this dazzling long formal prom dress by Alyce is a glamorous option for prom, gala, or a winning walk across a pageant stage. Imagine shimmering with every move you make in this two-piece evening dress that features a high-neck crop top and curve-enhancing long skirt. The eye-catching style has a bold keyhole detail on the fitted bodice with straps that lead to a trendy racerback enhanced with a flirty diamond-shaped cut out. A beaded waistband crowns the long skirt that skims the hips before flaring away from the knees and pooling into a dramatic train. It's hard to believe that this gorgeous sequin two-piece long formal prom dress, under $150, has such a low price tag.
