Kid Halloween Costumes and Spooky Decor for the Holiday

Dress them up as arguably Disney’s cutest character ever, Boo from "Monsters, Inc." This costume is a perfect imitation of the character dressed up in her own monster costume — googly eyes, mop hair, purple skin, and all. The only thing that could make this better? Matching Mike and Sulley costumes for the whole family. ($38.57, Walmart)

If your trick-or-treater isn’t old enough to truly appreciate their Halloween costume yet, this easy onesie is your safest route to getting them in the holiday spirit. Pair it with some footie leggings and soft pumpkin booties to keep them cozy. ($18.45, Amazon)

Because you’re never too young to get in the spirit. It’s made of 100% crocheted cotton and comes with a brown robe, bright green booties, gloves, and a hat featuring Baby Yoda’s droopy eyes and huge ears. It’s soft enough for your baby’s sensitive skin, and super breathable and lightweight so they won’t overheat. ($22.99, Amazon)

They’ll get a little lobster hat that fits babies age six to 18 months and a lobster carrier cover that attaches to your own baby carrier. And you’ll get a one-size-fits-all apron and chef’s hat for a coordinating costume that’s sure to have everyone smiling. Even if you’ve got a fussy baby and can just get in a pic for the ‘gram? Worth it. ($44.98, Oriental Trading)

And they can fit a variety of age ranges — one customer even had a kid, teen, and adult family member dress up in these getups. Just slip one of the grips over your head for the “scissors” costume, and use the shoulder straps and waist ties for “paper” and “rock.” ($35.94, Amazon)

This fun costume will be a delight for both you and your kiddo. It comes in three different sizes that’ll fit 2- to 10-year-olds and inflates with the included battery pack. Note that batteries aren’t included, so be sure to snag some AA batteries before the big day. ($39.99+, Amazon)

At least this one won’t drive the adults in the house crazy thanks to its song-optional design. This baby shark costume is made of soft fleece and comes with a sound chip that’ll play the tune we all know and love (or love to hate). It comes in three sizes — small, infant, and toddler — and you can also make it a family affair by snagging the matching mommy and daddy shark costumes while you’re at it. ($19.07+, Amazon) 

They’ll be the cutest cup of coffee around thanks to this costume’s overwhelming use of tulle (aka whipped cream). It comes with a little straw and whipped cream headband, plus a white and green tutu. Customers love the high-quality fabric, but rec sizing up for the perfect fit. Psst…if you want to match, wear a black shirt and pair it with this green apron to channel your inner barista. Grab a matching getup for your pup while you’re at it. ($20.99+, Amazon)

They’ll be the cutest Gryffindor you’ve ever seen. This costume comes with a one-piece dress that looks like the legendary Hogwarts shirt and skirt uniform and a cape in the colors of Hermoine’s house. All they need is their Ollivander’s wand, and then it’s Abracadabra. ($39.99+, HalloweenCostumes.com)

Why so serious? Your little one will put a smile on everyone’s face while trick-or-treating in the Joker’s iconic purple suit. This set comes with the entire three-piece suit (coat, vest, gloves, and all) and a Joker mask and wig to top it all off. ($56.99+, Amazon)

Help them channel their inner fairy with these gorgeous wings. They come in over 15 colors and have finger and neck straps so they’ll stay centered throughout the night. The set also comes with a lace mask and butterfly antenna to complete the look. ($16.99+, Amazon)

Darth Vader has never been more menacing. They’ll get a jumpsuit with attached boot covers, the iconic helmet mask, and a cape to channel one of the best villains in cinema. Snag them the matching red lightsaber and it’ll be the best Halloween yet. ($34.99+, HalloweenCostumes.com)

This fun Sonic jumpsuit comes with attached gloves and shoe covers and has the hedgehog’s iconic spiky hair and tail. And if you’re shopping for a bunch of Sonic lovers, snag them the Tails or Knuckles jumpsuits for an easy group costume. ($49.99, HalloweenCostumes.com)

Stick these all over the yard to get into the Halloween spirit. They come in a pack of four and are water-resistant and super durable, so you can reuse them year after year. Pro tip: Snag some mulch and dirt to create a mound in front of each gravestone for an extra dose of spooooky. ($17.99, Amazon)

These are not for the faint of heart (or stomach). They look like bloody fingers, eyeballs, ears, brains, and feet, and come individually wrapped so you can serve them on the big night, or at your Hallo-weekend parties. ($19.44, Amazon)

These come in a pack of three with an orange, black, and purple skeleton hand holding each cup. So whether you’re making Halloween punch or bloody ice cream sundaes for the kids, you can serve them all with a spooky twist. They’re also available as champagne flutes or shot glasses for the adult party. ($16/3-pack, Amazon)

You’ll get 10 reusable IV bags made from food-grade PVC to fill with themed drinks. This pack comes with a syringe, 10 labels, and 10 clip stoppers for on-theme, no-spill enjoyment. It’s also available in packs of 20 or 50. ($9.99+, Amazon)

Fake blood, of course. These are 16 inches tall and sport creepy phrases like “Beware,” “Keep Out,” and “Enter at Your Own Risk.” Since they’re water-resistant and easy to reassemble, you can reuse these holiday after holiday. ($16.99, Amazon)

You can’t go wrong with Hershey’s. This bag comes with 220 pieces of minis like Reese’s, Whoppers, KitKat, and more. Pop them in this holiday-themed bowl and leave them out for the taking. ($21.97, Amazon)
