Create a highly realistic premium fashion editorial portrait of a young adult woman sitting naturally on elegant outdoor stone stairs. POSE & COMPOSITION: The woman is seated casually on several wide stone steps, with one leg positioned slightly forward and the other bent naturally. Her knees are comfortably raised and her body has a relaxed, stylish posture. Both arms rest naturally across her knees, with her hands hanging softly and elegantly over the legs. Her shoulders are relaxed. Her upper body is slightly leaning forward toward the camera. She looks directly into the camera with a calm, confident and subtly alluring expression. Her head is slightly tilted toward one side, creating a sophisticated editorial pose. Maintain realistic human anatomy, natural body proportions, realistic arm and hand positioning, correctly formed fingers and joints, and natural interaction between her clothing and body. FACE & BEAUTY: Beautiful young adult woman with refined feminine facial features, symmetrical but naturally realistic face, expressive light-colored eyes, well-defined eyebrows, natural eyelashes, softly sculpted cheekbones, elegant nose, naturally shaped lips and subtle makeup. Makeup should be sophisticated and understated: smooth but realistic skin, subtle foundation, natural blush, softly defined eyes, delicate eyeliner, natural pink-nude lips and subtle highlights. Preserve realistic facial texture including natural pores, fine skin details and subtle tonal variations. Avoid excessive skin smoothing, plastic-looking skin or artificial beauty-filter effects. HAIR: Long, thick, naturally voluminous dark-to-medium brown hair falling over one side of her shoulder and partially framing her face. Hair should have realistic individual strands, natural volume, soft movement and subtle shine. The hairstyle should look professionally styled but not artificial. OUTFIT: She is wearing a premium fitted black leather biker jacket with realistic leather texture, subtle natural creases, stitching, metallic silver zippers, buttons and classic motorcycle-jacket detailing. Underneath the jacket, she wears a simple elegant black top with a subtle V-shaped neckline. She is wearing fitted dark charcoal/black slim jeans with realistic denim texture and natural folds around the knees and thighs. On her feet are premium black leather combat boots with thick platform soles, detailed lacing, metallic eyelets, realistic leather texture and subtle natural reflections. The complete outfit should feel modern, sophisticated, edgy, luxurious and fashion-forward. LOCATION & BACKGROUND: Set the scene on elegant weathered stone or marble outdoor stairs, resembling the entrance of a sophisticated historic building or upscale urban location. The background should contain softly blurred architectural details, stone railings and steps. Keep the environment realistic and visually rich but not distracting. Use a shallow depth of field so the woman remains the primary focus while the architectural background gradually falls into a beautiful natural blur. LIGHTING: Use soft natural daylight with cinematic directional lighting. The light should gently illuminate her face and hair while creating realistic highlights across the black leather jacket and boots. Maintain subtle shadows around the clothing folds, facial contours and stairs. Use balanced exposure, realistic skin tones and soft cinematic contrast. PHOTOGRAPHY: Premium professional fashion photography, luxury editorial aesthetic, realistic DSLR/mirrorless camera look, 85mm portrait lens aesthetic, shallow depth of field, realistic optical compression, crisp focus on the eyes and face, detailed clothing texture, natural bokeh, high dynamic range, subtle cinematic color grading. The image should look like an authentic professional fashion photograph rather than AI-generated artwork. FRAMING: Vertical full-body composition. Include the complete woman from head to boots while maintaining enough environmental context around her. Keep her centered slightly toward the middle of the frame. Do not crop the head, hands or boots. Maintain natural perspective and realistic proportions. IMAGE QUALITY: Ultra-photorealistic, extremely detailed, realistic skin texture, realistic hair strands, realistic leather and denim materials, physically accurate lighting, natural shadows, detailed stone texture, professional fashion photography, cinematic realism, sharp facial details, authentic photographic depth., aspect ratio 4:5
