Photorealistic boudoir portrait of a fictional adult woman, 27 years old, glossy black hair in a smooth low chignon held with a plain gold pin, smooth warm skin, polished makeup with wine-red lips, defined brows and a confident direct gaze, wearing wine-red satin corset lingerie set with gold lace trim and a sheer charcoal robe slipped off one shoulder, standing at a charcoal top shelf desk beneath the highest shelf of a tall bookcase with plain unlabelled boxes and a short plain ladder, warm gold side light, all surfaces completely plain with no lettering anywhere, elegant sensual atmosphere, soft cinematic light, tall portrait composition, high detail
