15 Halloween Onesies For Babies That Are So Cute It Hurts

Babies and Halloween costumes don't always go together, as much as you wish they did. Some babies will peacefully tolerate a costume all night long, while others will only wear theirs for a few hours, if at all. If they're not even willing to wear them, it might not be worth your while to go all out for Baby's first Halloween. In that case, it might be a better idea to look into Halloween onesies for babies that are so cute it hurts for the perfect themed outfit that your little one will wear all night long (or at least until they spit up or poop — babies, right?)

From sweet and pun-ridden to just a little bit cheeky, these Halloween onesies for babies are simultaneously low effort and a complete costume all in one. Many come in your choice of short or long-sleeved, which is great because then you can plan for the weather. With a pair of leggings or pants and maybe a little hoodie or cardigan, your baby will be the hit of the Halloween party, comfortable, and dressed for the weather of the day. There's a cute Halloween onesie out there for every baby, no matter your style or your budget.

This long-sleeved Halloween onesie is a great choice if you live in a colder climate, where your little one will likely have to be a bit bundled up on the big day. Paired with a pair of comfy pants, a sweater, and maybe a headband or hat, your baby will certainly be Halloween-ready.
