Satin cheongsam-clad woman turns, backlit, revealing high slit and leg

Photorealistic close-up fashion portrait of a young East Asian woman in a three-quarter rear view looking back over her shoulder, dark hair pulled back with a few loose strands framing her face, delicate features, subtle makeup, calm direct gaze. She wears a form-fitting silver-gray satin cheongsam with dark floral embroidery, high mandarin collar, sleeveless, delicate knot buttons at the waist, and an extremely high side slit from the hip all the way down, revealing her full leg and the curve of her hip. Body angled away from camera, torso slightly twisted, right hand resting lightly against her outer thigh, long fingers visible.
Nearly black background with faint light streaks and soft shadow patterns on the left side. Dramatic side-back lighting from the upper right creating strong rim highlights along her shoulder blade, arm, waist, hip, and exposed leg, high-contrast chiaroscuro with realistic skin sheen. Cinematic photography, accurate satin texture and reflections, ultra-detailed, 8K, sharp focus on fabric and skin.
