Create a highly realistic vertical 4:5 luxury evening portrait of a young woman posing in a sophisticated studio setting. She is turned slightly away from the camera, showing an elegant over-the-shoulder pose while looking back directly toward the camera with a confident, graceful expression. Her dark-brown hair is styled into a sleek low updo with a few soft face-framing strands around her cheeks. She has refined natural facial features, warm fair skin with realistic texture, expressive brown eyes, defined brows, subtle smoky burgundy eye makeup, soft blush, and deep rose-red glossy lips. She is wearing an elegant off-shoulder deep burgundy satin evening gown with a folded draped neckline and fitted silhouette. The back features delicate jeweled embellishments and a decorative sparkling detail. Add luxurious jewelry: a diamond necklace, dangling ruby-and-diamond earrings, multiple elegant rings, layered metallic bracelets, and a classic luxury wristwatch. Her nails are long and glossy with intricate deep-red and silver nail art. Her upper hand is posed delicately near her shoulder while the other rests naturally around her waist. Background is a rich dark burgundy studio wall with a soft cream-colored light area on one side, creating a dramatic two-tone backdrop. Cinematic warm lighting, soft highlights on the skin, subtle shadows, high-end jewelry campaign aesthetic, realistic fabric and jewelry details, natural hands and fingers, shallow depth of field, professional fashion photography, 85mm lens look, ultra-photorealistic, elegant and sophisticated, no text, no watermark.
