Dreamy Vertical Qipao Sofa Portrait

Create a tall 1:3 vertical cinematic portrait of {argument name="subject" default="a beautiful young East Asian woman"} reclining sideways on an antique floral upholstered sofa, her head resting on folded hands against the sofa back as she gazes softly toward the camera. She wears {argument name="outfit" default="a sleeveless pale silk qipao-style dress with muted watercolor floral patterns, a high collar, and a thigh-high side slit"}; her dark hair is styled in a loose low updo with soft face-framing strands, with delicate earrings and natural romantic makeup. The pose is elegant and intimate: upper body curled near the sofa arm, one bare shoulder visible, the long dress flowing down the frame, one leg partially visible through the slit in the lower foreground. Use {argument name="lighting style" default="warm diffused window light with hazy bloom"}, heavy soft focus, shallow depth of field, dreamy film grain, muted beige and cream tones, and a nostalgic boudoir editorial mood. Compose with the face in the upper-left third, the body extending diagonally downward through the very narrow frame, an overexposed white glow along the right edge like light leaking through a curtain, and blurred dark foreground vignetting on the left. Background should be minimal: a dim beige wall, soft shadows, and vintage fabric texture. Photorealistic, 85mm portrait lens feel, f/1.4 depth of field, painterly softness, no text, no watermark, no extra people.
