In shimmering metallic-jersey, this cowl-neck long prom dress offers a sophisticated look for your big night. The cowl-neck evening gown shines from the ruched bodice to the floor, while thin shoulder straps criss cross the open back before adjusting for a comfortable fit. Ruching continues through the waist of this tight formal dress, before smoothing over the hips and draping to the floor. From La Femme, this long designer dress offers a curve-hugging look for prom, galas, and other formal events.
