Create a Cannes-level luxury fashion advertising poster for an original couture house named "IVORY BLOOM". Use 100% live-action ultra-realistic editorial photography. Preserve the exact structural logic of the composition: a tall vertical poster, one adult female model in a soft close-up portrait placed centrally, her head slightly tilted and turned with a calm distant editorial expression, wearing a high-neck ivory dress, and a single oversized white peony blooming beside one side of her head as the key visual counterbalance. Set the entire image against a clean warm butter-cream background with no environmental clutter. The final image must feel like a collectible high-fashion magazine cover: poetic, aristocratic, soft, cinematic, and unforgettable. Style lock: ultra-real luxury fashion portrait photography, soft vintage editorial realism, prestige couture beauty campaign, clean studio-art background, no illustration, no CGI look, no plastic skin, no over-retouched beauty-filter effect. Core composition: tight upper-body portrait, model centered, face and flower occupying most of the frame, gentle negative space above for one oversized elegant master title only. No secondary text, no body copy, no footer, no side notes, no editorial paragraph, no logo block. Keep only one large refined English headline across the upper area as part of the composition. Suggested headline: "IVORY BLOOM". Model styling: adult woman with naturally pale luminous skin, soft auburn or light brown wispy hair loosely framing the face, refined red-brown lips, minimal couture makeup, and a high-neck ivory dress with smooth premium fabric and subtle sculptural folds. The body and face must remain elegant, natural, and anatomically correct. Flower styling: one large white peony with dense layered petals and a rich golden center, placed beside the model's head like a couture floral ornament. The flower must feel fresh, luxurious, soft, and monumental, acting as the main visual symbol after the face. Lighting: soft diffused frontal light with slight side shaping, delicate shadow transitions, gentle cheekbone definition, luminous skin, and creamy floral highlights. Keep the atmosphere airy, warm, and expensive, with no harsh shadows, no muddy darks, and no dead-black areas. Skin and realism: real human skin only, visible fine pores, subtle facial microtexture, faint vellus hair, realistic lip texture, natural tonal variation, slight under-eye translucency, delicate capillary warmth, soft semi-matte sheen, authentic live-action detail. No poreless skin, no waxy texture, no silicone appearance. Color strategy: restrained palette of butter cream, warm ivory, soft beige, petal white, muted auburn, and warm golden pollen tones. Keep the image minimal and harmonious, with the face and flower as the dominant focal points. Art direction goals: model-first hierarchy, couture floral symbolism, elegant title-driven poster composition, premium realism, flagship fashion impact, no clutter, no extra props, no copied branding, no watermark. Negative prompt: copied luxury brand name, copied masthead, copied paragraph text, any secondary text, body copy, footer copy, logo duplication, watermark, AI look, CGI skin, plastic skin, waxy skin, poreless face, over-retouched beauty filter, distorted facial anatomy, fake flower texture, low-resolution petals, muddy shadows, dead-black patches, black blotches, cluttered composition, cheap fashion poster look, cartoon rendering.
