Photorealistic fashion portrait of an adult woman, vertical frame 9:16, studio setting. Black background with one huge round white spotlight behind the model creating a 'moon disk' effect, high contrast, hard directional light, sharp shadow along the circle's edge. Model in half-turn with her back to the camera, head turned over the shoulder, gazing directly into the lens with a light sassy smile. Appearance: long wavy hair cascading to one side, glam makeup featuring glowing skin, subtle contouring, nude lips, and long voluminous lashes. Clothing is modest and elegant: a form-fitting black dress with an open back corset silhouette and thin straps, fully covered and appropriate. On her shoulders, a voluminous white feathered boa with highly detailed feather texture, soft fluff, and natural folds. Composition: model slightly offset to the left, light circle centered in the frame. Ultra realistic 8K, hyper-detailed, sharp focus; shallow depth of field with natural bokeh; HDR lighting; cinematic color grading; lens 85mm; aperture f/1.8; key light at 45 degrees, soft shadows; rim and back lighting for separation; clean white balance; natural skin texture with visible pores and glossy highlights. Negative prompt: nude, lingerie, nipples, see-through, explicit, overexposed, lowres, blurry, plastic skin, bad hands, extra fingers, artifacts, text, watermark, logo.
