Elegant Satin Dress Mirror Portrait

A young woman with fair skin, delicate natural facial features, and long dark brown hair styled in a loose ponytail. Several soft strands fall naturally around her face, giving her hairstyle a relaxed, effortless appearance. She has a calm, composed expression with a subtle neutral smile and is looking toward the smartphone screen while taking a mirror photograph. Her pose is casual and confident, with one hand holding a smartphone in front of the mirror and the other hand raised in a relaxed peace-sign gesture. She is wearing an elegant royal-blue satin dress with thin shoulder straps, a softly draped neckline, and a fitted silhouette with natural fabric folds and realistic satin reflections. The lower portion of the outfit features decorative blue feather-like trim, adding texture and a glamorous evening-fashion aesthetic. She carries a structured dark-blue handbag with a long gold chain strap. Her accessories include delicate layered necklaces, slim gold bracelets, and a few understated rings. Keep the overall styling polished, sophisticated, and tasteful. The scene takes place in a luxurious modern interior with a large full-length mirror surrounded by dark marble panels featuring subtle natural veining. The reflective surfaces create depth and an upscale atmosphere. Warm ambient interior lighting illuminates the subject softly from the front and sides, producing gentle highlights on the satin fabric, natural skin tones, and subtle reflections in the mirror. Maintain realistic shadows and believable reflective surfaces. Compose the image as a high-quality smartphone mirror portrait with the phone naturally visible in the foreground. Use realistic smartphone perspective, accurate mirror reflection, natural anatomy and proportions, detailed hands and fingers, realistic hair strands, and finely rendered clothing textures.
