Animals have ruled Saturday morning cartoons for decades. Bugs Bunny, Mickey Mouse, Scooby-Doo—the list goes on! If you're on the hunt for a unique Halloween costume idea that hails back to the heyday of cartoons on TV, look no further than Alvin and the Chipmunks. The Alvin Show originally dates back to the 1960s, but the cartoon had a comeback in the 80s, along with a series of movies and a new cartoon show in the 2010s. Alvin and the gang have sported a few different looks throughout the years, but they all stick to their signature colors. (Which makes these DIY Halloween costumes easy to recognize!) Keep reading and we'll show you how to make your own Alvin and the Chipmunks costume, along with Halloween costume ideas for the Chipettes.
