Create a 9:16 vertical photorealistic smartphone portrait of one clearly adult Chinese woman, age 25, standing in an elegant modern hotel suite near a large window. She wears a fitted black velvet floor-length evening gown with a very deep plunging V neckline, prominently emphasizing her full bust and natural cleavage while keeping nipples and areola fully covered by the dress. Three-quarter body framing, relaxed posture, one hand lightly touching her hair, calm confident expression, direct eye contact. Natural East Asian facial features, realistic body proportions, natural skin texture with pores and tiny imperfections, loose dark hair with subtle flyaways. Soft diffused daylight from the window, ordinary iPhone photo quality, mild smartphone sensor texture, slightly imperfect candid framing, background remains legible. Sophisticated, sensual, tasteful, believable real-life SNS photo. No text, no logo, no watermark. Avoid CGI, doll skin, plastic skin, exaggerated anatomy, huge eyes, studio lighting, artificial rim light, extreme bokeh, warped hands, extra fingers, duplicated jewelry, exposed nipples, visible areola.
