Elegant Woman in Black Dress by Spotlight and Disco Ball

An elegant woman in a floor-length black evening gown stands beside a large disco ball in a moody retro club. A sharp spotlight pours down from above, illuminating her silhouette with crisp, glamorous lighting. The dress is satin with a fitted bodice, a dramatic thigh-high slit, and a flowing train that pools at her feet. Her hair is styled in a sophisticated updo, and she wears minimal jewelry. The disco ball above swirls with reflected shards of light, casting silver and gold specks across her skin and the smoky atmosphere. The background hints at vintage neon with soft bokeh. The camera angle is three-quarters, slightly low, with a shallow depth of field to keep the focus on her face and dress. The mood is timeless glamour, red-carpet ready, cinematic and editorial. Rendering style: photorealistic, ultra-detailed textures, 8k, high-contrast lighting, rich blacks and metallic highlights.
