Design a portrait of a female model in luxurious lingerie, set against a rich, opulent background like velvet drapes or a polished marble floor. The model should have an elegant, curvaceous figure and be posed in a way that suggests confidence and allure. Use a medium aperture (f/4) for a balanced focus between the model and the background. Implement soft, diffused lighting to create a warm, inviting atmosphere, with a focus on flattering the model’s features and emphasizing the textures of the lingerie. The background should be dark with subtle, elegant patterns to keep the focus on the model.
