16 Adorable Baby Halloween Costumes You Can Buy Online

As far as we’re concerned, Cuddle Club’s Dino Onesie is the best onesie because it’s unisex, comes in four different colors (green, grey/black, purple/green, and pink/grey), and can easily blend into the pajama drawer after Oct. 31. Plus, because this baby Halloween costume is made with durable fleece, it’ll likely be warm enough to wear as-is while trick-or-treating (but of course pack a jacket just in case).

Any Wizard of Oz fans out there? InCharacter’s Lil’ Lion, tail bow and all, reminds us of Dorothy’s furry friend, only this king of the jungle is anything but cowardly; it’s cuddly, sweet, and full of giggles. The costume itself isn’t exactly heavy, but it’s made from polyester, and with a lot of different pieces involved, can get very warm, very fast.

There’s a wild thing in every growing babe; some just hide it better than others. (Until sugar’s involved; then all bets are off.) Unleash your little one’s inner beast on Halloween night with this majestic costume straight out of Maurice Sendak’s imagination. There’s really nothing monstrous about Leg Avenue’s cozy onesie. In fact, it’s multi-faceted. It can pass for a birthday suit or winter pajamas.  

For tiny babies 6 months and younger, this Baby Yoda costume may be even cuter than the first one. This is a hand woven costume, featuring 100% cotton, so it’s okay for Baby’s skin. It ships with the hat (with attached Yoda ears), the wrap, a belt, and green hands and feet. The crochet pattern delivers plenty of warmth for the baby on a cool Halloween night. For parents who are fans of Star Wars and The Mandalorian, this costume might be just the outfit for a set of first baby pictures. (Maybe to keep peace in the family, you had better use the christening gown your mother-in-law bought first, and then switch to this outfit later for some fun photos.) When it’s time for the kid to graduate high school 18 years down the road, and the school wants cute baby photos for the slideshow, you’ll have yours taken care of. No one in the slideshow will be as cute or hip as your Baby Yoda baby. (And we don’t want to hear any doubt about whether Baby Yoda will still be a worldwide phenomenon in 18 years. That’s blasphemy.)

This toddler-sized costume is perfect for the little unicorn in your life. Or just a toddler who really, really loves unicorns (and what kid doesn’t? Honestly what person doesn’t?)

Available in sizes 0-18 months, dress your little up as Carol Danvers, aka Captain Marvel! Honestly, we wouldn’t blame you if this was your baby’s daily uniform, too.

Oh look, it’s our dinner staple from college! Dress your baby up in this ramen costume, made of 100% cotton.

It’s baby Jack from The Incredibles! Note, this does not come with fire, lazers, or cookies. Or unsuspecting raccoons.

Even though you could probably DY this yourself with a white onesie, some cardboard, and green felt, it’s sooo much easier to just order this online and be done with it. Best of all? You can match with Baby by holding your very own (real) Starbucks latte in hand. Genisu!
