Sunlit Backless Fashion Portrait

Create a photorealistic full-body fashion portrait of a young adult woman standing indoors with her back mostly facing the viewer, near tall white French windows in a bright elegant living room. She has {argument name="hair color" default="soft medium brown"} shoulder-length slightly wavy bob hair with wispy bangs, and she turns her head over her right shoulder in a calm side-profile gaze toward the window, one hand gently touching the back of her hair. She wears a delicate {argument name="outfit color" default="warm ivory beige"} backless camisole-style top with very thin crisscross straps tied at the lower back, plus matching sheer wide-leg palazzo pants that drape to the floor, airy and semi-translucent but tasteful and editorial. The pose is graceful and natural, emphasizing an elegant back silhouette, relaxed shoulders, and soft feminine styling. The room is cream-toned and luxurious: a built-in bookshelf on the left with neatly arranged books, one framed photo, one decorative vase, and one small round ornament; a low cream sofa beneath it with exactly two cylindrical bolster pillows; large floor-to-ceiling French doors on the right with white mullions and brass handles; lush green garden foliage visible outside; polished light marble floor with subtle gray veining and sunlit window reflections. Use warm morning sunlight streaming through the windows, soft highlights, gentle shadows on the floor, shallow depth of field, realistic skin texture, natural proportions, high-end lifestyle photography, 85mm lens look, vertical 4:5 composition, bright airy beige palette, no text, no watermark, no extra people.
