A photorealistic full-body front-view portrait of a mature, tall, curvy woman standing upright in a cozy, festive living room. She has fair skin and a warm, genuine smile. Her hair is platinum blonde, cascading in loose, glossy waves down to her mid-back, softly framing her face and brushing her shoulders. Emerald green eyes sparkle with holiday cheer. She wears delicate red lace lingerie intricately patterned with tiny holly leaves and subtle gold embroidery – an elegant bra with slender straps tied in small velvet bows and matching high-waisted panties edged in scalloped lace. The room is alive with color: a grand Christmas tree behind her is draped in twinkling multicolored lights, shiny red and gold baubles, and handcrafted ornaments; wrapped gifts with bright ribbons are scattered at its base. A stone fireplace to her left holds a lush green wreath dotted with red berries and is topped by a garland of frosted pine branches and fairy lights. Soft lanterns and candles cast a warm glow on polished wooden floors and a plush white rug. The scene is lit with omni-directional illumination, eliminating harsh shadows and giving her skin a gentle, radiant sheen. Ultra-detailed, 8K resolution, shallow depth of field creating subtle bokeh from the Christmas lights for a fun, colorful, and heartwarming holiday atmosphere.
