ChatGPT Prompts for Adorable Halloween Pet Costume Photos

Every October my feed fills up with dogs in bedsheet ghosts and pugs dressed as pumpkins. And honestly, I never get tired of them.

The problem is that getting a real pet to sit still in a costume is a whole project. Some pets hate hats, some chew the cape off in ten seconds, and some just walk out of the frame. That is where ChatGPT helps.

Open ChatGPT, upload a clear photo of your pet, and paste any prompt below. ChatGPT keeps your pet’s face, fur color, and markings, and dresses them up in the costume. If you don’t want to upload a photo, just replace “the dog from the uploaded photo” with a breed, like “a golden retriever” or “a French bulldog”.

I kept the focus of every prompt on the costume itself. The backgrounds are simple on purpose, so the outfit and your pet stay the star of the photo.

1. Classic Bedsheet Ghost with a Pumpkin Bucket

This is the most loved Halloween pet look of all time, and it’s easy to see why. The eye holes and the little candy bucket do all the work.

Create a photo of the dog from the uploaded photo dressed as a classic bedsheet ghost. The costume is a plain white cotton sheet draped over the dog’s head and body, falling in soft loose folds all the way down to the ground and pooling around the paws. Two neat oval eye holes are cut out so the dog’s eyes and part of the ears peek through, and the nose and muzzle stick out from a small opening below. The dog sits upright and calm, holding the handle of a bright orange plastic jack-o’-lantern candy bucket gently in its mouth. The sheet has natural wrinkles and a slightly uneven hem for a homemade look. Shoot at eye level, centered, from a few feet away. Soft natural daylight from the side. The background is a simple wooden front door, slightly out of focus. Warm, cozy, and funny mood with white and orange as the main colors. Use aspect ratio 4:5.

Two small cream canvas drawstring sacks with a big black dollar sign printed on each sit on either side of the dog. The dog lies down on its belly with front paws stretched forward and looks straight into the camera with an innocent “who, me?” expression. Shoot from a slightly high angle looking down at the dog. Bright, even indoor daylight. The background is a plain light wooden floor. Playful, comedic mood with crisp black and white tones. Use aspect ratio 4:5.

Create a photo of the dog from the uploaded photo dressed as a giant bowl of fruity breakfast cereal. The dog wears a clear plastic cone collar around its neck that acts as the bowl, filled around the edges with oversized foam cereal rings in pastel orange, yellow, green, blue, and pink.

White and black skull-style face paint patterns frame the eyes and muzzle. The bones have a faint glow-in-the-dark green edge.
