Create an image of a smiling woman with vibrant red hair, standing by a window with natural light illuminating her face. She is wearing elegant black lingerie with lace details, and her expression is joyful and confident. The background should be softly blurred to keep the focus on the woman, with warm lighting enhancing the overall mood of the image. The setting should be indoors, with the window providing a soft, natural light that highlights her features and the texture of her hair and lingerie. The image should convey a sense of warmth, beauty, and confidence.
