Hyper-realistic cinematic portrait of a woman in a sapphire blue cowl-back slip gown on a Parisian rooftop

A detailed prompt for a hyper-realistic cinematic vertical portrait (9:16) of a woman, likely Polina Gagarina, viewed from the rear on a Parisian rooftop. It emphasizes the luxurious midnight sapphire silk-satin cowl-back slip gown, the pose (looking back over her shoulder), ethereal moonlight, and the Eiffel Tower glowing in the bokeh background.
