Photorealistic boudoir portrait of a fictional adult woman, 29 years old, dark chestnut hair in long polished waves over one shoulder, fair skin with a warm glow, groomed brows, defined cheekbones and a calm assured gaze, wearing ivory silk slip dress with slate lace trim and a sheer ice-blue duster robe worn open, seated at the plain writing desk, the closed blank-covered diary and a plain brass lamp beside her, soft cool evening light, all surfaces completely plain, no text anywhere, elegant sensual atmosphere, soft cinematic light, tall portrait composition, high detail
