Ritratto da studio accovacciata in maglia a righe e denim

An ultra-realistic, high-end fashion studio portrait, vertical 2:3, full-body medium composition. A young East Asian woman in her early twenties in a natural crouching pose, body slightly turned to the left, right knee raised and left leg naturally tucked in, both feet bare on the floor, one hand gently pulling the collar, the other resting naturally in front of the knee, head slightly tilted forward, gazing directly at the camera, calm, soft and natural expression, no forced smile, with a slight languor and approachability. Delicate oval face, small chin, almond-shaped dark brown eyes, soft straight eyebrows, natural long fine lashes, small nose bridge, nude pink lips. Cool-white slightly warm skin tone, preserving real pores, fine fuzz, slight tone variation and natural skin texture, no smoothing, no plastic feel. Long straight black hair, natural slightly off-center part, smooth hair over the shoulders, a few loose strands scattered naturally, ends gently drifting. Wearing a loose short blue-and-white horizontal-striped knit sweater, one side naturally slipping to reveal the left shoulder and collarbone, sleeves slightly long covering part of the hands; paired with dark blue high-waisted slightly flared jeans, cuffs naturally stacked, barefoot, no shoes or socks, no accessories. Background is a pure white seamless studio backdrop, minimalist and clean, without any props. Overall low saturation and low contrast, white background with slight warm-gray gradation.
