Halloween was once a day spent warding off the spirits of the dead. But — whew — it has evolved into a festival of trick-or-treating, parties and magical make-believe. The answer to the question “What are you going to be for Halloween?” was everything when we were kids. And in 2021? It’s just as important. Maybe even more.

To celebrate, we combed through the massive array of Halloween costumes for kids to find choices that’ll bring extra joy to the big day. Happy hunting. And haunting. Now let’s go get all the candy.
