A beautiful young Japanese woman with long straight black hair, fair skin, and cute innocent smile, posing elegantly in a photography studio. She is wearing a sleeveless black maxi dress with thin spaghetti straps, deep open back (backless design), high side slit on the left leg revealing her leg, flowing long skirt with pleats. Side-back view: she is turned slightly to the side, looking over her right shoulder with a gentle smile, right hand raised near her face touching her hair playfully, left hand holding the dress fabric near her waist. She is standing on one leg with the other slightly bent, wearing simple black sandals. Plain white seamless background, soft even studio lighting, high resolution, photorealistic, detailed fabric texture, natural pose, fashionable idol photoshoot style
