Cosmic Princess Halloween Costume Generator
A glowing star gown, a silver moon crown, and an observatory at night: a fantasy princess look without the sewing.
Example images on this page were generated with GPT Image 2 for Plain Upscaler. They show the intended direction, not a guaranteed result from every photo.
Edit your own photo into this look
Upload a portrait, keep or edit the prompt, and generate. The model works from your photo, so the result keeps your face and pose while changing the costume, hair, and scene.
Image editing runs on the existing Nano Banana editor. Clips are generated by the video model you choose, then cleaned up with the existing video upscaler.

About this look
Princess costumes are everywhere, but most of them look like party-store fabric under a phone flash. This preset leans into light instead: deep blue fabric, silver embroidery, and star patterns that appear to glow from inside the gown.
The result is a fantasy portrait rather than a scene from a specific game or film. That makes it flexible for Halloween parties, birthday shoots, and creator content while keeping the person recognizable.
Midnight-blue gown
Silver embroidery and realistic fabric folds give the dress weight instead of a flat costume look.
Glowing star patterns
The stars are soft and scattered, so they read as fabric detail rather than stickers.
Moonlit observatory
Tall windows, a starry sky, and blue rim light turn the portrait into a cinematic set.
Prompt recipe
Prompts stay in English because the image model follows English descriptions more reliably. Edit the prompt before you generate if you want a different background or lighting.
Use the uploaded photo as the primary reference. Preserve the subject’s recognizable facial identity, facial proportions, skin tone, approximate age, and natural anatomy. Transform the subject into an original celestial Halloween princess portrait. Replace the outfit with a midnight-blue fantasy gown featuring silver embroidery, softly glowing star patterns, and realistic flowing fabric. Add a delicate silver moon crown and luminous accessories. Place the subject inside a moonlit observatory with a starry sky visible through tall windows. Use elegant fantasy fashion photography, realistic fabric details, cinematic rim lighting, and a deep-blue, silver, and violet color palette. Keep the same number of people as the uploaded photo. Avoid altered facial identity, extra people, distorted anatomy, text, logos, and watermarks.
Turn the still into a short clip
Generate the portrait first, then use this prompt with an image-to-video model such as Wan 2.6 or Kling 2.6. Keep the first clip to five seconds and ask for small motion.
Image-to-video prompt
Use the provided image as the exact visual reference and starting composition. Create a continuous five-second cinematic fantasy portrait animation. Keep the subject’s face, crown, gown, and body proportions consistent with the reference. The subject slowly turns toward the camera while the star patterns on the gown shimmer softly. A gentle draft moves the outer layer of the gown. Distant stars drift slowly outside the observatory windows. The camera performs a slow, elegant push-in. Maintain realistic motion, stable anatomy, and consistent lighting. Do not change the person’s identity, replace the costume, add characters, or introduce sudden scene cuts. No text or watermarks.
The clip is generated by the video model you choose. Plain Upscaler's video upscaler can clean and enlarge the finished file; it does not animate the still by itself.
