A Made-Up Monster

When Disney and Pixar's Sulley needed to disguise Boo, he came up with an adorable monster costume. And with a few scraps he convinced everyone Boo was one of them. (Of course, her convincing roar helped!) The look was too adorable to ignore, so here we are offering you the same experience for your kiddo with our Disney Pixar Boo Monster Costume!

Design & Details

This delightful outfit features a full-coverage pullover tunic with a plush body, hood, arms, and foot covers. The sleeves include flip-back hand covers, while the hood sports soft-sculpted teeth along the opening, fiber-filled googly eyes on wired eyestalks, and chunky yarn hair. Embroidered clips down the back cleverly replicate Sulley and Boo's chosen fastener to complete the look.

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.

    So cute!
    By Prisma  | October 11, 2024
    Height 28 lbs | Weight 28 lbs | Size 12/18 Months
    This is perfect and even better in person. My daughter is 20 months but petite. I got a size 12/18 months and it fit her perfect. Such an authentic look. The costume is soft and the body is sort of padded for colder weather. The eyes are adjustable I just didn’t fix them.
    Bottom Line Yes, I would recommend this to a friend.

    Cute but not practical
    By Anonymous  | September 19, 2026
    This is a really cute costume for a toddler but impossible and uncomfortable to put on! It has no zippers or buttons or snaps, it’s just one very long piece that you have to wrestle over their heads- not made with toddler in mind, will be returning.
    Bottom Line No, I would not recommend this to a friend.

    Okay costume
    By Current Customer  | October 24, 2024
    Super cute idea but way too thick and hard to put on. No zipper or buttons. Bought it for my baby.
    Bottom Line No, I would not recommend this to a friend.
