"A fit adult woman in a tiny black triangle bikini stands on a sandy beach, her arms raised high above her head. Her hair is medium long with realistic texture. The background features calm water reflecting light blue to white gradients, suggesting bright early morning. In the distance, there are faint outlines of land or hills rendered as real-world terrain. The scene is illuminated by natural lighting, possibly golden hour, casting soft shadows on her skin and surroundings."
