## Output Contract
Generate a vertical 9:16 realistic fashion portrait of an adult woman standing in a Japanese urban apartment living room. Both arms raised behind her head, camera positioned 40–60 cm above the floor aimed slightly upward. Waist and thighs dominate the foreground; face and upper body in the upper center. Legs naturally cropped at the bottom edge. Overall impression: dignified and mature.

## Subject Lock

Chin slightly tucked, eyes looking down at the lens, relaxed eyebrows and mouth. Body type: healthy and mature with natural roundness and definition.

Pelvis slightly tilted right, weight on one leg, other knee relaxed. Fabric stretch, hem overlap, and side ribbon drape follow gravity.

## Composition & Camera
- 9:16 vertical format, low angle (40–60 cm), 24–28 mm equivalent wide-angle lens.

## Lighting & Palette
- Soft natural daylight from a large left window (black sash, white thin curtains).
- Light illuminates the contours of face, chest, abdomen, and left leg.
- Faint shadows on the right side; weak warm reflected light from wooden furniture.
- Ceiling slightly dark, creating a light-dark composition that draws attention to the subject.

- Outside window: blurred view of urban housing complex.

## Texture & Style
- Realistic photographic texture: natural skin, fine downy hair, soft shadows on abdomen and legs.
- Clear distinction between the ribbed top fabric and swim bottom material.
- Outlines not too sharp; soft three-dimensionality from natural light.
- High-quality fashion snap in an everyday indoor setting.
