For years, I’ve had tons of fun using plain pajama sets — like the ones you can find at Primary or Hanna Andersson — as the base for my kids’ Halloween costumes. With some head-to-toe monochromatic pajamas, all I’ve had to do is add some detail — a DIY that’s easy enough for me to pull off even with a busy schedule. I’ve cut strips of white duct tape to turn a basic black pajama set into a skeleton, and I’ve glued green triangles down the back of a red pair of pajamas to make a dragon.

What I love most about kids’ Halloween costumes made with pajamas is that oftentimes, you can transform simple pajamas into Halloween costumes even without gluing, taping, or sewing onto the PJs themselves. Which means your kids can keep on wearing the pajamas long after Halloween is over.

Kids' Halloween costumes made with pajamas | Crayons at The House that Lars Built

At The House That Lars Built, we found this fantastic idea to dress your kids as the crayons from one of our favorite books, The Day the Crayons Quit by Drew Daywalt. So brilliant. You can make this pajama costume even simpler by buying party hats in primary colors instead of making your own. BTW, we’ll be pinning this one for book character day at school too.

Kids' Halloween costumes made with pajamas | Bunny hat by Oeuf at Noble Carriage

I’ve been thinking about this adorable knit bunny hat by Oeuf ever since I found it at Noble Carriage, and I think pairing it with a pair of grey pajamas and these exquisite grey booties would turn your child into an adorable bunny for Halloween — or any day of the year, for that matter. This one isn’t cheap, but the cuteness is worth every penny. (They have unicorn and bambi hats too, and even more at Oeuf NYC.)

Kids' Halloween costumes made with pajamas | Care Bears at Say Yes

I still have a soft spot for the Care Bears, especially a costume as easy as this one I spotted at Say Yes. And you don’t even have to sew your own pilot’s cap, as their tutorial suggests. You can find those at Hanna Andersson or June and January, and hot glue gun on some felt or fleece ears.

Kids' Halloween costumes made with pajamas | Lumberjack at Little Inspirations

I’m dying over this adorable lumberjack costume at Little Inspiration. Unfortunately, we couldn’t find anyone who sells these tree-stamped red pajamas, but it seems easy enough to DIY. Stamp a plain pair of red thermal pajamas with black fabric paint, or go with this cozy lumberjack sleeper at Hanna Andersson for a readymade look. The black beanie, beard, and boots are really the signature musts of this look.

We’ve seen hundreds of sandwich-board style costumes on Pinterest, but this Dragon Loves Tacos siblings costumes at Hello, Wonderful is my absolute favorite.

Even if Ghostbusters isn’t your style, though, click through to her site — she has very easy tutorials to turn your littlest ones into superheroes, soda bottles, and (as shown at the very top) three blind mice, too.
