502Celestial Dress Editorial

Generate the image now. Output exactly one finished celestial dress fashion editorial, no prose.
MEDIUM IS A PRIMARY REQUIREMENT: read the Background field's medium and apply it to the ENTIRE image, especially face, hands and dress, not just scenery. Ink/cel illustration means visibly hand-drawn dark contours, flat jewel-color fills and sharply separated graphic shadow shapes; no realistic skin or photographic shading. Gouache painting means visibly opaque matte pigment, broad broken brush marks, simplified painted facial planes and dry-brush fabric folds throughout; no glossy realistic model over a painted backdrop. Dimensional rendering means sculptural three-dimensional forms, frosted translucent materials and physically rendered textile. Photography is used only if the background explicitly asks for it or specifies no medium. A fashion editorial describes the SUBJECT, never overrides the chosen medium. Make all those treatments unmistakably different at thumbnail size. Choose a fresh distinctive adult face, hairstyle and pose suited to the setting; do not default to the same dark-haired model in every scene.
Canvas: Output size 1080x1350 pixels, 4:5 portrait, Instagram standard.. Default 4:5 portrait. Full-bleed artwork, no border, collage, magazine cover, mockup or inset.
Dress color: 【Dress color】. Blank means midnight blue. Use this as the dominant fabric color, keeping embroidered stars and nebulae luminous and visible.
Background: 【Background】. Blank means a moonlit reflecting pool. Interpret the setting, light and any material or medium words in this value to give the editorial a coherent visual treatment; preserve the celestial couture subject in every treatment.
Invent one original adult female fashion model aged at least 25, with distinctive natural mature features unrelated to any real person or celebrity. Do not use an attached person's identity. Invent an original wearable floor-length couture gown: opaque fitted bodice, structured folds, layered skirt and a flowing train. Fill the fabric with intricate embroidered star clusters, branching silver filaments, scattered crystalline beads and softly luminous nebula clouds woven INTO the textile. Show seams, fabric weight and believable draping; the nebula must follow the folds rather than float as a flat galaxy pasted over the model. Use asymmetrical large and small star groupings, never repetitive wallpaper. Keep the face, shoulders, two arms, two natural hands and gown silhouette clear. The model is the only person; her complete hairstyle and the substantial skirt and train are visible. A deliberate fashion pose, strong face and garment focal points, layered depth and subordinate setting, rich material detail with clear tonal separation. Fill the frame with the model, sculptural dress and environment. Vary pose and visual treatment to suit the chosen background while delivering the same celestial dress editorial subject.
