A photorealistic gravure-style portrait of a fictional adult Japanese woman, age 20, very cute idol-like face, soft feminine facial features, natural healthy body, naturally full upper-body silhouette under clothing, realistic upper-body proportions, natural skin texture, no AI-looking skin.

She is wearing a soft white yukata-inspired robe with a deep V neckline, decorated with delicate pale pink floral patterns, lightly wrapped to create a tasteful and elegant natural bust shape under clothing, with realistic gravity, soft fabric tension, and relaxed fabric drape. A dark navy obi-style sash with subtle floral patterns is tied around her waist. The outfit looks like a real fabric version of an elegant floral yukata, slightly glamorous but still refined and classy.

Hairstyle: dark brown hair, loosely tied in a low side bun / soft updo, with a few wispy strands framing her face, small pink ribbon accessory near the bun. Expression: gentle, calm, slightly shy, soft eyes, subtle natural smile. Pose: upper body portrait, turned slightly sideways, looking back softly toward the camera, subtle sensual pose, graceful neckline and shoulders.

Scene: standing by a window indoors, warm soft sunlight streaming in from behind and the side, dreamy golden-hour atmosphere, soft highlights on hair and skin, a bright airy background with a quiet Japanese room feel. Mood: elegant, romantic, clean gravure aesthetic, natural iPhone-style realism mixed with professional portrait quality.

Composition: medium close-up, vertical framing, focus on face, hair, neckline, and outfit details, shallow depth of field, realistic lighting, imperfect real-life atmosphere, photorealistic Japanese gravure portrait, highly detailed fabric texture, realistic skin pores, soft cinematic color grading.
