A medium shot, eye-level portrait of a 20-year-old woman with a youthful, delicate face and a slender build, positioned centrally against a neutral, soft-focus background. She possesses long, flowing black hair that cascades down her shoulders and deep, expressive black eyes that gaze gently at the viewer. Her expression is serene and poised, embodying a refined, "seiso" beauty. She is dressed in a soft, airy white one-piece dress made of lightweight fabric that drapes loosely around her frame, with her hands resting lightly and naturally in her lap. The visual style features clean linework and a gentle color palette, with smooth, glossy skin tones and a soft, luminous glow. The atmosphere is pure and tranquil, emphasized by a shallow depth of field and soft, natural lighting that enhances the ethereal quality of the scene.
