I feel like when it comes to Halloween, there are really only two kinds of people in the world: those who plan and meticulously design their DIY Halloween costumes ……..and the rest of us.

With Halloween just around the corner, I thought I’d do something crazy and actually plan my costume a little earlier than an hour before trick-or-treaters arrive, but still not put a lot of time or money into it.

But even if it’s October 30th when you read this, don’t stress because I’ve got you covered! Each of these adorable DIY Halloween costumes costs less than twenty dollars to make.

That’s right…… under $20.00

On top of that, all of these simple DIY Halloween costumes can be created in a single afternoon. Some outfits only require some inexpensive accessories to complete the costume with items you already have. No matter which one you choose, this year you have a plan and not waste hours of your time making it!

To read the full directions and tutorial for each costume, click the link in bold just above each image to be redirected to the blogger’s DIY post who created the costume. Show them some love and have a Happy Halloween!
