Emerald silk gown catches warm golden glow in grand ballroom

A cinematic, high-fashion full-body portrait of an elegant woman sitting gracefully on an ornate vintage velvet sofa inside a lavish European palace ballroom. She is wearing a luxurious, deep emerald green silk-satin sweetheart neckline gown with a dramatic thigh-high slit and a flowing train. She accessorizes with black opera-length satin gloves, a sparkling diamond necklace, and delicate gold strappy high heels. Her long, dark brown hair is styled in soft, voluminous vintage waves. The opulent background features grand marble columns, a large crystal chandelier casting a warm golden glow, a polished mirror reflecting the room, and a marble fireplace with a gentle fire burning. Rich Persian rug on the floor, dramatic chiaroscuro lighting, sophisticated cinematic composition, 8k resolution, photorealistic.
