Full body shot of a 28-year-old Japanese woman with long black hair, wearing navy blue panties. The subject is fully submerged underwater in an indoor pool, appearing cheerful with a bright expression. The woman and her clothing are soaking wet, with the navy blue panties appearing as deep, saturated, water-heavy fabric clinging to her skin, showing realistic wet texture, water sheen, and dark tones from saturation. The scene is captured underwater with clear, refractive lighting illuminating the subject and the pool environment. High-detail photorealistic composition showing the entire body and face, crisp underwater clarity, natural skin tones, and fluid hair motion.
