A cinematic soft-focus portrait of a woman from behind and slightly in profile, framed from the upper torso up in a vertical composition. She has {argument name="hair color" default="dark brown"} hair styled in a loose messy updo with wispy strands catching the light. Her face is mostly hidden by her pose and hair, with only a small portion of one cheek visible. She wears a {argument name="dress color" default="deep red"} sleeveless dress with an open back or low-cut side, emphasizing her bare shoulder and upper back. One hand is raised delicately near her neck or shoulder, fingers relaxed. Use strong warm backlighting and rim light, with glowing golden highlights around the hair and skin, dreamy lens flare, and large circular bokeh in the blurred background. The image should feel intimate, elegant, and slightly sensual, like a high-end fashion or beauty editorial, with shallow depth of field, creamy blur, warm amber and rose tones, and a soft cinematic glow.
