Destined to shine, this strapless long prom dress sparkles with rhinestone beading. Structured corset boning supports the strapless neckline of this beaded-bodice prom dress. A thigh-high side slit parts the floor-length skirt just below the flattering asymmetrical pleating on this corset prom dress. A train trails behind and adds a final dash of runway flair. Priced under $250, this strapless pleated prom dress is a steal of a luxury formal design that's exclusively sold at PromGirl.
