Photorealistic boudoir portrait of a fictional adult woman, 27 years old, glossy black hair in a smooth low bun held with a plain silver clip, smooth warm skin, polished makeup with defined brows and a confident direct gaze, wearing slate-blue satin corset lingerie set with ice-white lace trim and a sheer pale-grey robe slipped off one shoulder, standing in a slate-blue room at tall windows beside a plain writing desk holding one closed cloth-bound diary with a completely blank cover, no title or lettering anywhere, cool ice light, elegant sensual atmosphere, soft cinematic light, tall portrait composition, high detail
