Photorealistic vertical smartphone mirror selfie of an adult

Photorealistic vertical smartphone mirror selfie of an adult woman standing casually in a bright, modern white-tiled bathroom. She has long, voluminous dark-brown hair styled in loose natural waves, softly framing her face. Her expression is relaxed and slightly playful, with her eyes looking toward the phone screen. She is wearing an elegant light turquoise-blue satin wrap dress with a V-neckline, cinched waist, flowing skirt, and loose semi-sheer bell sleeves with delicate lace-like detailing. The fabric has realistic satin texture and subtle natural folds. She holds a modern silver-gray smartphone in one hand at face level, partially covering one side of her face, while her other arm rests naturally by her side. The image is captured through a large rectangular bathroom mirror, with realistic mirror reflections and slight smartphone-camera perspective. Background: clean contemporary white bathroom with glossy rectangular wall tiles, a white bathtub or shower area, a neatly folded white towel hanging on a rail, minimal fixtures, and bright soft daylight entering from the side. Include subtle realistic reflections and small imperfections on the mirror for an authentic candid photograph.
