Trick-or-Treating Theory

It's just a theory. But if Disney and Pixar's Sulley was able to protect Boo from being discovered with a quickly-created monster costume, warming all of our hearts in the process, a real baby in a similar style is likely to have an amazing Halloween! Try it out with our licensed Disney Pixar Monsters Inc. Boo Monster Costume!

Signature Style Recreated

This outfit includes a pullover tunic and shoe covers made for comfort and easy dressing. The cuddle plush tunic makes Boo's signature look extra cozy. But the details ensure it perfectly recreates the style starting with a hood featuring soft-sculpted teeth, plush googly eyes on wired eyestalks, and chunky yarn hair. Sleeves with flip-back hand covers provide the cutest tentacles, and embroidered clips down the back add a clever touch.

Questions & Answers

Q: The eyes on the top of this costume look really big. If I get the 0-3 size will they still be really big on top of her head? And my baby will be 3months exactly on Halloween. Would you recommend 0-3 or 3-6. (1 Answer)
Asked by Anonymous | October 3, 2026
Monster Responds...
Those fiber-filled eyeballs with embroidered eyes are attached to the hood, so they sit on top of the head the same way in every size. For sizing, the 0-3 has an 18" front length and a 20" chest, while the 3-6 measures 20" front length and a 21" chest. At exactly 3 months, the 3-6 could give her a little more room to grow into it, which is worth considering since babies change fast. Comparing her current measurements to our size chart is the surest way to land on the right fit.

Q: Will the 0-3months size be oversized or does it fit just right? I have a preemie baby right now and I don’t know how much big she will get before Halloween. I don’t want it to be too big and cover her completely. (1 Answer)
Asked by Stephanie  | August 18, 2026
Monster Responds...
That's such a sweet question, and congratulations on your little one! The 0/3 month size has an 18" front length, a 20" chest, and a 21.5" waist, so comparing those numbers to your baby's actual measurements as she grows will be the surest way to judge the fit before Halloween.

Q: How do I wash the costume? (1 Answer)
Asked by Paulina  | October 13, 2024
Monster Responds...
The care instructions aren't something our copy covers for this costume, so here's what we do know to help you make a safe call: the main body is 93% polyester and 7% spandex, the sleeves are 95% polyester and 5% spandex, and the lining is 100% polyester. For polyester and spandex blends like these, a gentle cold-water machine wash or hand wash is generally the safest approach, and tumble drying on low or air drying helps protect the cuddle plush fabric, fiber filling, and the posable wires in the hood.

Q: What size is the little girl wearing on the picture? Does the costume run true to size or big or small? (1 Answer)
Asked by Liza | October 10, 2024
Monster Responds...
We can't tell which size the model is wearing from the photos alone. For fit, our size chart is the most reliable guide: compare your little one's chest measurement to the bodysuit chest column, which runs from 20 inches at 0/3 months up to 23.5 inches at 12/18 months. If their measurement falls between two sizes, we'd suggest going with the larger one.

Q: Baby boo monsters inc costume
Size 6/9
Can I preorder before Halloween since this product says “coming soon”? (1 Answer)
Asked by Item # FUN7359IN | October 8, 2024
Monster Responds...
Yes, you can add a "coming soon" item to your order before it's available to ship. The 6/9 month size has a 22" chest, 23" waist, and 6" bootie length, so it's worth comparing those to your little one's measurements to make sure it's the right fit.
