Hotel Bathroom Mirror Selfie

Live-action fashion photography of an adult woman sitting sideways on the edge of a washstand counter in a luxury hotel bathroom, taking a mirror selfie that showcases her back. Captured in a 9:16 vertical orientation, framing from her head down to mid-thigh, occupying the center to left of the frame. She holds a [latest generation triple-camera smartphone in Desert Gold] in her right hand at face height, aimed toward the mirror on the right. She has a calm, mature expression with natural translucence, looking down slightly at her phone screen. Her hair is a [glossy dark chocolate brown bob cut just below the jaw] with slightly inward-curving ends, thin wispy bangs softly framing her cheeks. Her makeup features pale pink-beige blush, subtle brown eye makeup, natural under-eye contour, and glossy rose-beige lips. She wears [a summer mini dress made of fine ivory white ribbed material that naturally follows the body's lines] with a modest V-neckline and a deep open V-back extending from shoulder blades to waist, highlighting smooth, elegant back lines. Her upper body is slightly twisted, pulling her left shoulder toward the mirror while her waist rests on the counter with legs trailing to the right. Setting: High-end bathroom with beige marble tiles, a glass shower booth, greige vanity cabinetry, a white ceramic bowl basin, and polished chrome fixtures. Soft, warm ceiling downlights and mirror backlighting gently illuminate her face, shoulders, and back, casting gentle shadows under the counter. Natural 50mm perspective, crisp focus on face and smartphone, softly blurred background. Authentic smartphone photo feel with realistic skin texture, fabric ribbing, and subtle reflections on marble and metal, avoiding over-retouching.
