Selfie looks

Two Halloween AI prompts for one person and a close, clear photo. Both keep the face and change the outfit, the hair and the whole scene.

Original photo: smiling woman with dark hair in a cream hoodie taking a selfie — Original

Selfie · Fantasy

Cosmic Princess

A gown that looks like a deep blue starfield, a crystal tiara and silver star earrings, on a balcony floating above a violet nebula. Pure fantasy, no spooky edge.

Her face held, but the open grin became a softer closed smile and her loose hair turned into a long braid. The close selfie also became a full-length shot. Add waist-up portrait if you want the face bigger.

Prompt

Use the uploaded photo as the primary reference. Preserve the subject's recognizable face, skin tone, approximate age and natural anatomy. Transform the subject into an original cosmic princess: a flowing gown whose fabric looks like a deep blue starfield, a delicate crystal tiara and small silver star earrings. Place her on a balcony floating above a violet nebula. Photorealistic fantasy portrait, natural skin, soft glowing light. Keep the same number of people as the uploaded photo. Avoid altered facial identity, extra limbs, text, logos and watermarks.

Original photo: smiling woman with short silver hair in a red rain jacket — Original

Selfie · Autumn fantasy

Lantern Fairy

Amber wings veined like dry maple leaves, a shawl of copper leaves and a paper lantern glowing in her hands, in a dusky grove full of fireflies.

The closest match of the seven: same face, same short silver hair, same warm smile. The trees came out as red maples rather than oaks, which nobody will mind.

Prompt

Use the uploaded photo as the primary reference. Preserve the subject's recognizable face, short silver hair, approximate age and natural anatomy. Transform her into an original autumn lantern fairy: delicate amber-veined wings like dry maple leaves, a shawl of woven copper leaves and a small paper lantern glowing in her hands. Place her in a dusky oak grove with fireflies. Photorealistic fantasy portrait, natural skin, warm lantern light. Keep one person. Avoid altered facial identity, text, logos and watermarks.

Costume looks

For a costume you might really make or rent. The prompt keeps the face uncovered so you can judge how it would look on you.

Costume · Homemade

Cardboard Robot

A silver-painted box body with bottle-cap buttons and a blinking light, dryer-vent tube arms and an antenna headband, at a garage party under orange string lights.

His face, stubble and half smile came through almost unchanged, and the box looks like real cardboard. Two extra party guests appeared behind him; add no other people in the background if you want him alone.

Prompt

Use the uploaded photo as the primary reference. Preserve the subject's recognizable face, hairstyle, skin tone and natural anatomy; keep the face uncovered. Dress the subject in a homemade Halloween robot costume: a silver-painted cardboard box body with bottle-cap buttons and a small blinking light, flexible dryer-vent tube arms and a cardboard antenna headband. Place him at a garage Halloween party with orange string lights. Photorealistic, playful, real cardboard texture. Keep the same number of people as the uploaded photo. Avoid altered facial identity, text, logos and watermarks.

Original photo: smiling man with short locs in a plaid shirt — Original

Man in a full-length white plush unicorn mascot suit with a glowing violet horn and lilac mane on a foggy dark stage

Costume · Playful spooky

Haunted Unicorn Mascot

A fluffy off-white plush suit with a stitched grin on the hood, a glowing violet horn and a tangled lilac mane, alone on a foggy stage under one spotlight.

The suit, horn and mane are all there and he kept his big smile. The catch: it is a full-length shot, so his face is small inside the hood. Ask for a waist-up portrait to see the face clearly.

Prompt

Use the uploaded photo as the primary reference. Preserve the subject's recognizable face, skin tone and natural anatomy; keep the face uncovered and visible through the open mascot hood. Dress the subject in an original haunted unicorn mascot costume: a fluffy off-white plush suit with a stitched grin on the hood, a softly glowing violet horn and a tangled lilac mane. Place him on a dark school stage with fog and a single spotlight. Playful-spooky, photorealistic, real plush texture. Keep the same number of people as the uploaded photo. Avoid altered facial identity, gore, text, logos and watermarks.

Pet looks

Halloween AI prompts for a dog or a cat. Both name the fur, the eyes and the markings so the animal stays your animal.

Original photo: golden retriever sitting on a wooden porch with autumn leaves — Original

Pet · Dog

Pumpkin Pet

A soft knitted orange pumpkin costume with a little green stem hat, in a sunny pumpkin patch with straw bales all around.

Same golden dog, same open-mouth smile. The costume came out as a knitted orange sweater rather than a round pumpkin body. Ask for a round, stuffed pumpkin body if you want the full shape.

Prompt

Use the uploaded photo as the primary reference. Keep the same dog: same breed, face, fur color and markings, eyes and expression. Dress the dog in a soft knitted orange pumpkin costume with a little green stem hat. Place the dog in a pumpkin patch on a sunny autumn afternoon surrounded by pumpkins and straw. Photorealistic pet photography, natural fur, correct dog anatomy. Keep one dog. Avoid extra legs, distorted anatomy, text, logos and watermarks.

Original photo: black cat with amber eyes lying on a wooden windowsill — Original

Black cat with amber eyes under a white ghost sheet on a porch step next to a jack-o-lantern candy bucket

Pet · Cat

Ghost Sheet Cat

A tiny classic white ghost sheet with the face poking out, on a porch step at dusk next to a pumpkin candy bucket and fallen leaves.

Black fur and amber eyes held. The sheet covered the ears, so the face looks a little cut-out. Add ears poking through two small holes to keep the cat shape.

Prompt

Use the uploaded photo as the primary reference. Keep the same cat: same black fur, amber eyes and face; keep the face visible. Drape the cat in a tiny classic white ghost sheet with the head poking out through a round opening, sitting on a porch step beside a trick-or-treat bucket and fallen leaves at dusk. Photorealistic pet photography, natural fur, correct cat anatomy. Keep one cat. Avoid extra legs, text, logos and watermarks.

Couple looks

Halloween AI prompts for two people in one photo work best when you say clearly who wears what, the woman and the man or the person on the left.

Original photo: older couple hugging on a seaside boardwalk, she in a red jacket, he in a tan coat — Original

Older couple in a moonlit statue garden, she in a green snake crown and emerald gown, he in a grey coat with a grey tint to his skin

Couple · Mythic

Gorgon and Statue

She becomes a gorgon with a crown of sculpted green snakes and an emerald gown; he becomes the statue she turned to stone, in a moonlit garden of old statues.

Her half worked well and both faces, his glasses and their hug held. His half did not: he came out in a grey wool coat with faint cracks, not painted stone. Try every part of him carved from grey stone, including the coat, no fabric.

Prompt

Use the uploaded photo of the couple as the primary reference. Preserve both people's recognizable faces, glasses, ages and the way they stand together. Turn them into an original mythic couple costume: the woman as a gorgon with a crown of sculpted green snakes and an emerald draped gown; the man as her stone statue, his skin, hair, beard and clothes painted pale grey stone with fine cracks, smiling. Place them in an overgrown moonlit garden with old statues. Photorealistic costume photography. Keep exactly two people. Avoid gore, altered faces, text, logos and watermarks.

How to write Halloween AI prompts that keep your face

Good Halloween AI prompts follow the same four parts in the same order: keep the identity, say what changes, name the place and light, then list what to avoid. Here is the Lantern Fairy prompt taken apart.

Questions about Halloween AI prompts and photo edits

How do I use Halloween AI prompts on my own photo?

Upload a clear photo to the box at the top, press Use this look on a card or paste a prompt, then press Generate. Halloween AI prompts with a keep-the-face line change the outfit and scene while you stay recognisable.

Can I use these prompts in Gemini?

Yes, they are plain text, so you can paste them into any Gemini-based editor. The box here already runs Nano Banana 2, Google's Gemini image editor. Results in other apps can still differ a little, because each app has its own settings.

Are there free AI Halloween prompts and a free generator?

The prompts are free to copy and use anywhere. Making the picture on Monipix is not free: it needs a subscription or a one-time credit pack, and the free monthly credits cover photo upscaling only. Each picture costs 8 credits at 2K or 5 at 1K.

Why does my result not look like me?

Usually the photo is small, dark or side-on, or the keep-the-face line was removed. Use a sharp front-facing picture, keep the first sentence of the prompt and ask for a waist-up portrait, since full-length shots make the face smaller.

What makes good Halloween photo prompts?

Concrete things beat moods. The best Halloween AI prompts name the costume pieces, the place and the light, and finish with what to avoid. Change one part at a time, so you can tell which edit fixed or broke the picture.

Can I write a prompt in my own language?

You can edit any word of these prompts or type your own. We keep the cards in English so the text matches the pictures shown. Whatever language you use, keep the same four parts: who stays, what changes, where, what to avoid.

Which AI made the pictures on this page?

The box starts on Nano Banana 2, Google's image editor, and you can switch to Nano Banana Pro, GPT Image 2 or Seedream above. Our examples were made with the earlier Nano Banana, so your results can differ a little from the cards.

Can I use a celebrity or famous character in a prompt?

We only show original looks and ask you not to copy a real person's face or a protected character. Describe a style instead, such as a cosmic princess or a stone statue. Only upload photos of yourself or adults who agreed, never children; every face here is fictional.
