Halloween was my favorite holiday when I was little! This collection of 75+ DIY kids Halloween costumes are so cute, you’ll just have to make one. This is a great list that includes costumes for babies, girls, and boys.
I think the whole reason to have a child is to dress him or her up for Halloween. KIDDING! But seriously, mini costumes are way cuter than those for adults, don’t you think?
I particularly love the costumes that incorporate felt, hoodies, or part of a child’s existing wardrobe because those materials are inexpensive and readily available. Plus you can make something at the last minute. And I don’t know about you, but I’m a last minute person.
But I’ll let you decide your favorite. I’ve put together a collection of over 75 DIY kids Halloween costumes for you to enjoy. What are your children going to be this Halloween?
