A young adult woman sits on a gray fabric sofa against a warm white indoor wall, with a small white square light switch visible on the left. She wears a deep navy sleeveless high-neck ribbed knit dress. The dress is fitted but everyday-looking, with clear vertical rib texture, natural stretching across the torso, and realistic folds around the waist and skirt hem. She has a simple gold hoop earring and long side-parted cool-brown wavy hair, softly falling across one side of her face and shoulder, with a few real flyaway strands. She leans slightly back on the sofa, her head gently tilted upward while her eyes look downward into the camera. Her expression is calm, cool, relaxed, and unsmiling. The camera is placed low, around knee level, shooting upward in a vertical 9:16 smartphone frame. One thigh and knee sit close to the lens and dominate the lower foreground, creating strong perspective depth, while her face sits in the upper half of the frame with a large area of blank wall above. Visible skin includes the face, a small area of neck, shoulders, upper arms, forearms, hand edges, knees, front thighs, and part of the inner thigh area. The chest is fully covered by the high-neck knit dress, while the waist, abdomen, back, hips, and buttock-adjacent areas are hidden by the clothing and seated pose. Her skin is fair with a neutral pink undertone, creamy in the highlights and softly beige-gray in the shadows. It should feel fine, soft, clean, and lightly matte, like thin foundation plus a subtle soft-focus filter, while still keeping natural tonal variation on the arms and legs. Lighting is soft indoor diffused light or window light from the front-left, evenly illuminating the face, shoulders, arms, and foreground leg. The pale wall reflects gentle brightness, while the gray sofa and dark navy dress add contrast. Keep the image close to a real smartphone social-media portrait: slight beauty retouching, mild sharpening, visible knit texture, sofa fabric texture, flyaway hair, low-angle perspective distortion, and a simple imperfect crop. Avoid making the outfit revealing, changing the high neckline, exaggerating body curves, plastic skin, childlike proportions, distorted limbs, harsh flash, or a cluttered background.
