Here's a beautiful long prom gown with an attached off-the-shoulder shawl that adds a look of romance. The gorgeous strapless long formal dress sparkles with glitter-tulle designs from the sweetheart neckline to the floor, while a sheer shawl drapes over the upper arms before attaching at the back. The glitter evening gown has a fully-lined long skirt with a sheer overlay that shimmers down to the floor in a flattering a-line shape that completes the design. Surprisingly under $200, this off-the-shoulder long prom ball gown offers a first-class look without blowing the budget.
