Woman in Sequin Dress on Marble Stairs

Realistic and cinematic portrait of a [Japanese woman], approximately [20 years old], sitting gracefully on the polished marble stairs of a modern luxury hotel at night. She is wearing a [silver sequin mini dress], silver strappy high-heeled sandals, and delicate silver heart-shaped earrings. Her legs are crossed naturally, and she has a calm, poised expression, glancing softly to the right. Effortlessly styled hair, natural skin texture, and anatomically accurate hands and fingers. 16:9 horizontal composition, with the subject positioned on the right third of the frame, leaving open negative space on the left featuring a dark glass wall with soft, warm city bokeh. Ambient warm indoor illumination mixed with gentle side lighting highlights the sparkling silver reflections on her sequin dress and heels. Highly detailed marble veining, sleek glass railings, and an atmosphere of refined quiet luxury. No text, logos, watermarks, deformed hands, or overly smoothed synthetic skin.
