This post is inspired by my first nephew who is due about a week after Halloween! He won’t be here in time to dress up in a costume but we will be ready for next Halloween with lots of adorable Onesie Costume ideas!
I just co-hosted a Star Wars baby shower for my brother and sister-in-law this weekend, so I figured it was the perfect time to share these adorable onesie costumes for babies.
Adorable Onesie Costume Ideas
Babies wear adorable onesies all year long, so how do you up the game at Halloween? Turn one of those onesies into a costume with a few simple or elaborate additions.
My sweet pencil onesie costume was accomplished by adding simple duct tape to a yellow onesie and a pink knit cap. Simple and adorable, perfect for a teacher’s baby!
This baby Waldo onesie costume is super fun. It’s also perfect for a teacher or anyone that loves to read!
Fun DIY Onesie Costumes
If DIY isn’t your thing, it’s pretty easy to buy a cute Halloween Onesie and add an adorable Halloween Tutu. Or up your game and create this No-Sew Princess Baby Costume with a little effort.
I think this Fisher Price stacking toy costume is the cutest! It’s simply a decorated onesie with a fun little hat to finish it off. Another simple onesie idea is this magic 8 ball baby costume!
I made this Olaf costume using a hoodie and it works well for toddlers and school-age kids. If you want a baby snowman, check out this DIY Olaf Onesie Costume. Pair it with a stuffed Sven and I think you have a pair cuter than Anna and Elsa!
I don’t usually think of Cruella as cute but this DIY Cruella de Vil Baby Onesie costume somehow is! Maybe it’s the tutu! In fact, it’d be cute to add a tutu to this DIY Superhero Baby Costume too!
