Photorealistic boudoir portrait of a fictional 27-year-old adult woman, long dark waves over one shoulder with a plain clear-bead pin, warm tan skin, self-assured mature features and a calm direct gaze, wearing a white satin and lace lingerie set with a sheer sky-blue robe slipped off both shoulders, standing in a bright studio beside a plain clear glass triangular prism on a plain stand with no markings, soft daylight, elegant confident pose, tall portrait composition, no text, no watermark, no logo, no brand marks
