A contemporary dress on a mannequin, with ankle-length, flowing satin layers, modest full sleeves, and a fitted bodice with subtle embroidery details. The fabric is a rich deep emerald with delicate sheen. The background shows a rooftop terrace at dusk, decorated with string lights, modern lounge seating, and a panoramic city skyline illuminated with neon signs. Include soft shadows, realistic lighting reflections on the fabric, and high-resolution texture. No human figure or revealing elements.
