What you can make

How it works

1. Pick the silhouette, not the character

   Describe the shape and mood you want: horned mascot, braided antihero, glowing princess, retro robot. Original wording avoids copyright problems and gives the model more room.

2. Use a clear photo

   Front-facing, even light, visible shoulders, no sunglasses. A good source keeps the face stable while the costume changes.

3. Protect the face first

   List face, skin tone, age, body proportions, pose, and the number of people. Only then describe the costume.

4. Set the scene and light

   A moonlit garden, a candlelit hallway, or a studio backdrop. One light idea keeps the costume readable.

Costume preview formula

Use this structure as a checklist. Replace the bracketed fields, keep the protection lines, and remove anything that does not apply to your shot.

Use the uploaded photo as the primary reference.
Preserve: face, facial proportions, skin tone, age, body proportions, pose, and number of people.
Costume: [original look, materials, colors, accessories].
Scene: [location, time of day, atmosphere].
Camera and light: [portrait framing, key light, rim light].
Avoid: altered identity, extra people, extra limbs, distorted hands, text, logos, watermarks.

• Describe an original look, not a named film or game character. Copyrighted characters invite refusals and legal risk.
• Build the costume in layers: hair, garment, accessories, makeup, background. One pass can handle a coherent look; five passes should each change one layer.
• Keep the face recognizable. A costume preview is only useful if you can see yourself in it.
• Add a lifestyle scene. A costume on a plain background is harder to judge than one in moonlight or candlelight.
