How it works

Upload your photo

Drop your image into EditThisPic. JPG, PNG, WebP up to 7MB. Full body shots work best for complete costumes. Upper body is fine for costumes focused on the top half like pirate coats or superhero capes.

Expect: Simple costume change: 30-40 seconds. Detailed costumes with props or armor: 45-60 seconds and may need refinements.
Describe the costume you want

Type what you want: 'change to a medieval knight in full plate armor with a red cape' or 'put a Victorian-era dress with lace collar and bustle on this person.' Be specific about era, style, and signature details. No marking needed—the AI understands costume descriptions.

Tip: Name the era or character type specifically: 'Viking warrior', '1920s flapper', 'samurai' rather than vague 'historical costume.'

Review the transformation

Check that the costume looks convincing on the body. Look for correct proportions, authentic details for the era or character, and that the costume follows the body shape naturally.
Refine with markers if needed

If specific costume elements like armor pieces, capes, or accessories need adjustment, tap markers on those areas and regenerate. Most costumes look great on the first try.

Tip: Markers are for precision refinement only. Try without them first—you usually won't need them.

"We do themed family photos every Halloween. Instead of buying 5 costumes, I uploaded our group photo and generated different theme options. The kids voted on their favorites, and we only bought what we actually needed." @CostumeMom_Rachel

If something looks off

AI changed the wrong area or something I didn't want changed

Why: The AI couldn't determine which areas to transform, especially if the costume description could apply to multiple body areas or if props overlap with the body.

Try: Tap markers on the specific areas you want the costume applied to, then regenerate with the same prompt

Try This →

Tip: Markers tell the AI 'I mean THIS area specifically.' Use them when description alone is ambiguous.

Costume looks generic or not historically accurate

Why: Broad descriptions like 'medieval outfit' give the AI too much creative freedom. More specific period and style details produce authentic results.

Try: change to a [specific era] [specific type] costume with [2-3 authentic details that define this period]

Try This →

Tip: Research one or two signature details: 'Elizabethan ruff collar', 'Roman gladiator greaves', 'samurai kabuto helmet.'

Armor, helmet, or props look unrealistic

Why: Hard surfaces like metal armor and helmets are harder for the AI to render with proper reflections and material texture than soft fabrics.

Try: change to the costume with realistic metal armor that has visible reflections, scratches, and worn texture

Try This →

Tip: Adding 'worn', 'battle-scarred', or 'polished' gives the AI material texture cues for more realistic armor.

Face or hair changed along with the costume

Why: Some costumes include hairstyle changes (like wigs or headwear). The AI may alter facial features if the costume traditionally includes face makeup.

Try: change the costume only, keep the face, hair, and features exactly as the original photo

Try This →

Tip: Add 'keep original face and hair' to prevent unwanted facial changes with character costumes.

Costume proportions are off—too bulky or too tight

Why: Character costumes vary wildly in silhouette. Without body-fit guidance, the AI may pick proportions that don't match the original body.

Try: change to the costume with proportions that naturally fit this person's body shape, not oversized or unnaturally tight

Try This →

Tip: For bulky costumes like armor, add 'fitted to the body shape' to prevent the costume from looking like it's floating.

Quick answers

Do I need to mark my body before changing the costume?

No! Just describe the costume: 'change to a medieval knight armor' or 'put a pirate costume on this person.' The AI understands costume descriptions and applies them to the body. Only use markers if the AI changes the wrong area on the first try.

How do I change to a specific character costume from a movie or show?

Click '+ Add reference image' and upload an image of the character's costume. Then type 'change to the costume from the reference image.' The AI matches the outfit's design and details. Describe distinctive elements like 'red cape' or 'leather armor' for more accuracy.
