Photorealistic boudoir portrait of a fictional adult woman, 28 years old, glossy black hair in a smooth low chignon held with a plain violet resin pin, smooth fair skin, polished makeup with wine-red lips, defined brows and a confident direct gaze, wearing violet satin corset lingerie set with charcoal lace trim and a sheer black robe slipped off one shoulder, standing within a plain stone arch at a midnight-violet realm desk with concentric plain rings set into the floor and heavy draped curtains at the sides, moody violet side light, all surfaces completely plain with no text or markings anywhere, elegant sensual atmosphere, soft cinematic light, tall portrait composition, high detail
