An authentic, casual vertical 3:4 smartphone mirror selfie. A clearly adult woman stands against a plain warm off-white wall, with a deep-black chin-length bob and thick straight bangs. She holds a dark triple-camera phone in front of her face, obscuring most facial features. Facing the mirror with a slight turn through her torso, she stands with her legs naturally apart. She wears a black short-sleeved cropped T-shirt with its hem lifted to reveal her waist and abdomen, paired with plain black high-cut bikini-style briefs. Preserve natural, full body contours, fabric creases, subtle variation in skin tone, and realistic skin texture. Broad, soft indoor light produces faint shadows; slight softness and fine grain give the image an everyday phone-photo quality. Center the subject with empty space above her head and crop the feet at the lower edge. Keep the background bare and avoid polished studio lighting.
