Robes de soirée bleues dramatiques - mannequin de mode

Create an image featuring a professional fashion model wearing a striking, vibrant royal blue one-shoulder gown with an elegant, dramatic floor-length cape sleeve. The subject should be captured in a high-fashion studio setting with a dark, moody background and sharp, cinematic spotlighting that creates a rim light effect. Incorporate a mix of poses, including a poised, confident stance with hands on hips, and a dynamic movement where the model's hair is caught mid-air, all while maintaining a sophisticated aesthetic and a rich color palette.
