Generate a 9:16 vertical portrait photo with realistic photography quality in a high-end urban rooftop style, overall clear, bright, and refined, with a modern city high-rise building background and fashionable street-photography feel.

The subject is a young adult East Asian woman aged 20-26, standing with her back to the camera in front of a glass railing on a high-rise rooftop, hands resting naturally on the railing, body slightly leaning forward as if gazing at the distant city in the sunlight. The figure has a clear adult feminine quality — not childlike, not vulgar, not exaggerated. She has light blue long wavy hair, smooth and voluminous, falling naturally to around the waist with soft waves at the ends, appearing lightweight and translucent blue in sunlight, with black bow hair accessories on both sides for an elegant, dreamy effect.

The figure has a mature, full-figured but naturally proportioned curvy body shape, with soft shoulder and neck lines, a defined waistline, natural waist-hip transition, and long leg proportions, presenting an elegant S-curve back silhouette. The focus is on the overall body silhouette, garment tailoring, leg lines, hair texture, sunlight reflection, and urban spatial relationships — not individual body parts.

She wears a clean white long-sleeve top paired with a gray-white plaid high-waist mini skirt with subtle irregular layering and natural folds, lightweight material with full coverage, overall look young, fashionable, and fresh. The legs wear high-gloss light skin-tone stockings with a delicate, smooth, reflective horse-oil stocking texture, with natural highlight lines along the legs that are realistic but restrained. Black patent leather high heels with deep red sole details complete the urban fashion look.

The scene is on a modern city high-rise rooftop, with a transparent glass railing in the foreground, distant building facades and window grid reflections, sunlight entering the frame from a side-upper angle casting clear light and shadow on the ground. The overall background is clean, modern, and spatially layered, with slight reflections in the glass railing and slightly blurred but structurally real city buildings.

The composition is a full-body back-view shot, camera positioned slightly below and behind the subject, emphasizing the long hair, waistline, skirt layering, leg proportions, and heel lines. The figure occupies the lower-center of the frame with the cityscape in the background, creating a strong urban fashion atmosphere. The image allows high-end commercial portrait retouching quality, with delicate and realistic skin and stocking highlights, genuine fabric folds, natural hair strand layering, overall refined, clear, eye-catching but not vulgar.
