Reference image: uploaded photo. Do not change facial features. Ultra high-definition fashion portrait, vertical format 9:16. A striking editorial Christmas portrait of a young woman posed in a luxurious holiday setting. The woman stands beside a decorated Christmas tree, body slightly angled, one arm raised elegantly holding a red glass ornament, the other hand resting on her hip, creating a sculptural hourglass silhouette. Confident, poised posture with emphasis on waist and elongated lines. Hairstyle: polished vintage-inspired updo with volume at the crown, smooth sides, and precisely sculpted baby hairs along the hairline, sleek and refined, classic Hollywood glamour styling. Makeup: flawless even complexion with soft luminous finish, sculpted cheekbones, bold satin red lipstick, clean sharp eyeliner, softly blended eyeshadow, voluminous lashes, defined elegant brows. Outfit: long evening gown (as in the uploaded photo, without any changes), strapless structured corset-style bodice emphasizing the torso, smooth satin-like fabric with subtle sheen, fitted silhouette flowing into a long elegant skirt, couture-level tailoring. Accessories: diamond choker necklace and matching earrings, minimal and luxurious. Environment: classic Christmas atmosphere with a lush green Christmas tree decorated with red and gold ornaments, wrapped gift boxes in red, white, and gold tones placed at the base of the tree, deep red velvet curtain backdrop creating a rich theatrical mood. Lighting: soft warm studio lighting highlighting the face, neckline, and dress texture, gentle shadows sculpting the body, cinematic and balanced, no harsh contrast. Composition emphasizes posture, gown structure, and festive luxury, background sharp and clear, not blurred. Style: high-end fashion editorial with glamour, holiday elegance, confidence, slight film grain for a magazine-quality finish. Do not change facial features.
