Create a high-resolution, photorealistic image of a confident, mature woman in her 50s or 60s modeling elegant lingerie in a sophisticated and stylish bedroom setting. The woman exudes grace and self-assurance, with a natural, radiant smile. She is wearing an elegant, tasteful matching set of lace lingerie in a soft, pastel color that complements her skin tone. The bedroom features chic, modern décor with a neutral color palette, including a plush bed with a tufted headboard, silk sheets, and decorative pillows. Soft, natural light filters through sheer curtains, casting a gentle glow over the scene. A large mirror on one wall reflects the woman's image, enhancing the sense of space and elegance. Fresh flowers in a vase on a bedside table add a touch of freshness and femininity. The overall image should evoke a sense of confidence, beauty, and the timeless elegance of mature femininity.
