Flowy, flirty, and fabulous, this sheer-corset long a-line prom dress named Yasmin by Velvi is as affordable as it is gorgeous. At under $100, you can slip into this long tulle evening gown with an eye-catching sheer corset that wraps around to the back for a fitted look at prom, galas, and other formal events. In misses and some plus sizes, this long formal dress has thin shoulder straps that lead to the midrise open back, while the fully-lined long skirt has a sheer tulle overlay that opens in a side slit before ending at the floor. A small train completes the look of this classic long prom ball gown that is as glamorous as it is budget friendly.
