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.

If you’re looking for fun, last-minute costume ideas that are easy to make and comfy for kids to wear, check out these awesome ideas.

Pop culture Halloween costumes for kids: Serena Williams at Primary

First off…pro tip.

How perfect is this baby Serena Halloween costume made from a black baby dress or sleep gown! Or, use a pair of black baby footie pajamas and let the black baby tutu do the work. Just add a hair piece, and maybe some white booties or baby sneakers. They have full instructions on their DIY blog.

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