Stunning backless dress portrait

Create a portrait of a high-fashion editor with a vertical composition, featuring a glamorous woman who possesses {argument name="hair color" default="Flowing reddish-brown long hair"} She stood with three-quarters of her back to the camera, glancing back, her face deliberately obscured by a warm brown, opaque square veil that matched her skin tone. She wore a highly dramatic outfit.{argument name="dress color" default="black"} The backless evening gown features a halter neckline, pleated drapes at the waist and hips, and a metallic finish.{argument name="metallic accent color" default="gold"} Fabric embellishments wrap around her chest and waist. Her hair flows to the left as if caressed by a gentle breeze, adorned with elegant jewelry, including a dangling earring and a ring. She is placed against a backdrop of a large, abstract textured painting, featuring thick, impasto brushstrokes, palette knife relief effects, and warm autumnal hues: ochre, bronze, gold, rust red, burnt orange, cream, taupe, and smoky brown. Warm, directional studio lighting from the upper left creates soft shadows, realistic skin texture, glossy fabric highlights, and a luxurious gallery atmosphere. The framing extends from mid-thigh upwards, with a slightly right-leaning composition emphasizing the open back and silhouette. Photorealistic fashion photography, 4:5 vertical aspect ratio, rich contrast, painterly background, no visible text, no watermark.
