5 DIY Kids’ Halloween Costumes Using a Cardboard Box

share this:

If you’re anything like us, you’re probably wondering what to do with all those cardboard boxes you unintentionally collect – or intentionally collect, because you just LOVE how cute thredUP’s boxes are. (Nudge, nudge. Wink, wink.)

Anyway, we have an idea! Make an original, one-of-a-kind Halloween costume for your kid this year (win all the contests PLUS save tons of money and resources). The planet will thank you, and so will your kiddo, hopefully.

Check out our roundUP below of kids’ costumes you can easily make out of a cardboard box. And if you feel like a #lazymom when it comes to your own costume, don’t worry! We have seven all black costumes that you can make in about 30 seconds. Thrift on!
