A photorealistic, ultra-detailed 8K image of a mature, tall, curvy woman standing upright in a festive Christmas setting, front view. She has fair skin that glows warmly in omni lighting, striking emerald green eyes, and long platinum blonde hair flowing in soft, loose waves down to her mid-back with a gentle side part. She wears a matching red lace lingerie set with delicate floral embroidery, scalloped edges, satin ribbons, and sheer panels, paired with thigh-high stockings held by lace garters. Her posture is confident and playful, weight shifted to one hip, arms relaxed at her sides, and a bright, genuine smile lighting up her face. Behind her, a richly decorated Christmas tree with twinkling fairy lights, colorful baubles, gold garlands, and wrapped presents creates a fun, colorful atmosphere. Warm candlelight flickers from a nearby mantle adorned with holly and stockings, while vibrant shadows and highlights sculpt her curves and the intricate lace details. The scene is alive with festive color – deep reds, emerald greens, shimmering golds – and captures a joyful holiday spirit in a crisp, clean environment, shot with a 50mm lens at f/1.8 for a softly blurred background that keeps all focus on her in sharp, captivating clarity.
