Undoubtedly the star of the show, this gorgeous sheer-corset high-low prom dress is sold exclusively at PromGirl. With a sheer embellished corset that wraps around to the back, this long high-low formal dress gets a flirty look for prom, galas, and other black-tie events. The long prom ball gown has a high-low tulle skirt that gathers at the waist before cascading into a mini hemline in front that gradually tapers to the floor in the back. A thigh-high side slit and a small train provide the sultry allure that makes this long high-low prom dress one that no one will soon forget.
