A photorealistic natural fashion portrait of a fictional 20-year-old adult Japanese woman, clearly adult, not based on any real person. She has a cute “seiso-kei gyaru” look: a Japanese idol-like cute face with a clean refined gyaru vibe, large natural brown eyes, softly defined eyeliner, subtle lashes, natural glossy lips, soft pink blush, gentle elegant expression, slight natural facial asymmetry, realistic pores, slight skin imperfections, not overly symmetrical, not plastic skin. She is wearing a bold black strap-style bandeau corset top made of multiple horizontal black bands across the torso, each band featuring white sport-style lettering and large white buckle closures, creating an edgy fashion look while still styled as a clean fashionable street outfit. The top has structured cutout spaces between the bands, with the bust securely covered in a tasteful way. She also wears a loose black faux-leather jacket draped off both arms and hanging around her elbows, black high-waisted fitted pants, and layered chunky silver chain necklaces around her neck. Pose and composition: her face must be fully visible in the frame. Medium shot to medium-close fashion composition including her head, face, upper body, waist, and part of the thighs. She is seated in a confident relaxed pose against a white textured wall, legs slightly apart in a natural fashion pose, torso angled slightly toward the camera, shoulders relaxed. One hand is lightly lifting or holding the edge of the black jacket, the other arm relaxed. She looks directly at the camera with a calm, slightly cool but cute expression. The bust, waist, and outfit details are clearly visible, while the face remains an important focal point. Body and styling: healthy natural body, slim waist, feminine silhouette, soft natural bust with realistic weight and natural roundness, not exaggerated, not balloon-like. The strap top fits naturally with subtle fabric tension and realistic structure. Strong but clean fashion mood, clean gravure-like realism, tasteful sensuality, realistic skin texture, high detail. Setting and lighting: simple white textured wall background, indoor or studio-like fashion snapshot atmosphere, clean bright lighting with soft shadows, realistic contrast on the black outfit and silver accessories, high-resolution photorealistic natural photo, not anime, not illustration, not overly retouched.
