Anime Idol Costume Design Sheet — Sora 2 Prompt

Create a full costume reference sheet with front/side/back views, color palettes, fabric details, and accessory breakdowns for anime school idol characters. Use it as a コンセプトアート starting point for GPT Image 2: keep the visual structure and style constraints intact, then swap in your own subject, brand, or scene.

This prompt is organized as structured JSON with fields such as type, document info, and layout. Keeping that hierarchy helps the model separate the subject, layout, interface elements, and detail constraints.

Start with small changes to subject, scene, camera, and color, then generate a few variations to compare composition and detail without turning the page copy into keyword stuffing.
