Young woman with blue hair in bikini top in autumn park

Photorealistic portrait of a young woman with long, straight blue hair and fair skin, wearing a white bikini top with tiny pink accents and a small white flower accessory at the strap. She stands in an autumn park with golden leaves and warm sunlight, looking directly at the camera with a calm, neutral expression. Background features shallow depth of field and soft bokeh. Natural daylight, gentle shadows. Shot with a 50mm lens at f/1.8 for cinematic realism, high detail, and lifelike textures on skin and hair. Slight breeze moves her hair, subtle makeup, no visible jewelry, vibrant yet natural colors.
