Write a Halloween Costume AI Prompt That Matches Your Clothes

A useful Halloween costume AI prompt names the clothing to replace, points to its reference image and states what should stay unchanged. Adapt one of the five briefs below to your actual clothes, then use it as optional additional instruction alongside the two required photos.

Use these starting briefs with one single-person photo and one clothing reference. Text supplements the images. Keep this clothing edit focused on one person; plan makeup, props and scenery separately.

Give each image one job

Upload one photo of one person for identity, pose and scene, plus a separate clothing reference for the replacement. Frame the person to show the intended clothing area. Use another model’s reference for clothes only. A preset supplies a starting brief; both images remain required.

Build the instruction around the visible garment

Name the garment and visible details, then specify what stays. Remove anything absent from the reference.

PartWhat to write
TargetReplace only [the jacket / visible outfit].
ReferenceUse [the garment] in the clothing reference.
DetailsRetain its visible [collar, sleeves, closure, hem or print].
PreserveKeep the person, pose, other clothes, lighting and background.

Adapt a costume brief to the clothes you can see

These briefs match the tool presets. Adapt them to your two images and keep the final text below 600 characters. Copy it into Additional instructions. Sources below explain clothing choices; none validates this editor’s output.

Forest witch

Use the witch outfit in the clothing reference: its long robe, cape, colors and fastening. Keep the reference layer order and sleeve shape. Retain the original person, visible face, hair, pose and background. Make a fully clothed fashion photo. Do not add face paint or a new scene.

Show the robe from neckline to hem, with the cape open enough to see the layers. Compare the cape edges, sleeve openings and the face with your original. Use preset.

Velvet vampire

Replace the visible clothing with the vampire costume shown in the outfit reference. Prioritize its high-collared cape, lining, waistcoat and shirt. Keep the person’s face, hair, skin tone, pose and background close to the original. Keep the face uncovered; do not add fangs, blood or makeup.

Choose a clear front view showing the collar, cape lining and waistcoat separately. Check the collar around the jaw, the shirt opening and the cape over the shoulders. Use preset.

Pirate captain

Dress the person in the pirate clothing from the outfit reference. Keep the shirt, long coat, belt placement and visible fabric colors close to that reference. Preserve the original face, hair, pose, hands and scene as closely as possible. Do not copy the reference person or add weapons and props.

Use an unobstructed outfit view with the shirt, coat front and belt clearly separated. Look at the belt crossing, coat buttons and any hands overlapping the sleeves. Use preset.

Graphic skeleton

Use the black skeleton-print clothing in the outfit reference. Follow the visible bone-print placement across the top, sleeves and trousers, within the original framing. Keep the original person’s face, hair, pose and background. Keep the face uncovered; do not replace skin with bones or add skull makeup.

Use a straight-on photo of the actual printed clothing, with both sleeves visible. Compare the rib pattern, left and right sleeves, knees and any gaps in the print. Use preset.

Midnight gothic

Use the gothic dress from the clothing reference, following its high neckline, long sleeves, fitted waist, hem and trim. Keep the original person’s face, hair, body proportions, pose and background as close as possible. Keep the clothing opaque and fully covering; do not add makeup or change the scene.

Choose one complete dress reference that shows the neckline, waist and hem in even light. Inspect the lace edges, neckline, sleeve length and dark fabric against the background. Use preset.

Narrow the brief when changing one piece

To change only the pirate shirt, write “Replace only the shirt with the shirt in the clothing reference.” Keep the existing trousers, footwear and outer layers. Choose a reference exposing the whole shirt; a covering vest hides its construction.

For different sleeves or a collar, choose a matching reference. Change one clothing decision at a time.

Compare with the original before keeping a result

Keep both untouched inputs beside the result. Preservation requests cannot guarantee unchanged pixels. If identity or scene changes, return to the original images for another attempt.

Checks to make before saving.On a narrow screen, each label is followed by its full answer.

What changedWhat to inspect or revise
Face or bodyCompare expression, hairline, hands, proportions and pose.
Merged layersCheck cuffs, collar, cape closure and waist; expose their boundaries in the reference.
Altered printInspect ribs, lace and lettering; replace a folded or unclear reference.
Extra editsReject unwanted makeup, teeth, props, lighting or background changes.

Reusing text drafted for another tool

Text drafted in ChatGPT or Gemini, or copied from a Midjourney prompt, still needs to match this editor’s two-image workflow. Remove product-specific commands, scenes, makeup and extra subjects. Another service’s advertised effects do not establish support here.

Choose a look in the costume ideas. For other clothing edits, see the general prompt guide.
