Style: Photorealistic luxury evening fashion photography, elegant bridal couture editorial, cinematic candid aesthetic Subject: A woman wearing an exquisite champagne-white, asymmetrical embellished evening gown with a fitted silhouette, sheer flowing overskirt, and delicate sparkling jewelry. Setting: A grand, dimly lit interior staircase with dark polished steps, black architectural walls, and a sleek metallic handrail. Lighting: Focused overhead lighting, soft highlights on the sequins, subtle shadows, and a dramatic low-light atmosphere. Create an image of a woman descending an elegant staircase in a breathtaking champagne-white couture gown featuring an asymmetrical one-shoulder neckline, a sculpted fitted bodice, intricate crystal beadwork, delicate shimmering embellishments, and layers of sheer translucent fabric cascading into a dramatic flowing train. Add a high slit partially revealed beneath the airy overskirt, creating graceful movement as she steps forward in elegant metallic high-heeled sandals. Style her hair in a sophisticated updo with a few loose strands framing her face, complemented by sparkling drop earrings, a delicate statement necklace, and refined bracelets. Capture the full-length figure from a high, diagonal overhead angle as she looks downward with a poised, serene expression. Surround her with dark architectural lines, polished staircase surfaces, and a metallic handrail, emphasizing the contrast between the luminous gown and shadowy setting, realistic fabric textures, subtle film grain, and understated luxury, vertical portrait format 3:4. Negative prompt: no text, no watermark, no logo, no distorted hands, no extra fingers, no malformed anatomy, no duplicated limbs, no unnatural staircase perspective, no stiff fabric, no excessive sparkle, no oversaturated colors, no harsh flash, no blurry subject, no cartoon effects.
