A fictional 20-year-old adult Japanese woman, clearly adult, photorealistic natural photo, tasteful beach gravure style, clean summer resort mood. She has a Japanese idol-like cute face with a slightly glamorous gyaru softness, small softly rounded oval face, clear dark brown eyes looking directly at the camera, delicate straight eyebrows, small refined nose, glossy soft pink lips, a gentle confident smile, natural facial asymmetry, realistic pores, slight skin imperfections, natural skin texture, not overly symmetrical, not plastic skin. Her hair is long dark brown with soft waves, with subtle teal-green inner color strands near one side, falling naturally around her shoulders. She is standing on a sunny beach near the ocean, warm golden-hour sunlight, soft blue sky, blurred sea and sand in the background, relaxed summer vacation atmosphere. The camera is close and slightly above chest height, vertical medium shot from head to hips, shallow depth of field, natural smartphone-photo realism mixed with clean magazine gravure lighting. She faces the camera with her upper body slightly angled forward, shoulders relaxed, both hands gently holding the brim of a white woven wide-brim sun hat, smiling softly. She wears a sage green triangle bikini with tasteful coverage, thin shoulder straps, soft fabric texture, and natural folds. Over it, she wears an open white waffle-knit zip hoodie, loose and soft, sleeves covering part of her hands, front open to show the swimwear in a clean resort fashion way. Matching sage green bikini bottoms with side ties are visible at the waist. Large natural bust with soft natural fullness, natural gravity, natural roundness, subtle fabric tension in the bikini top, realistic body proportions, healthy slim waist, smooth natural contours. Emphasize the contrast between the white hat, white textured hoodie, sage green swimwear, warm beach light, ocean background, and soft summer smile. High-resolution realistic photography, clean subtle sensual mood, no nudity, no nipples, no explicit exposure, no vulgar pose.
