The Snapchat face swap filter has been around for a while now — but we finally found the perfect use for it. Sure, it's fun to hang out with friends and swap faces — you know, just to see what you would look like. And it's even more fun when celebrities share their face swap pics, especially when things go hilariously wrong. But you know what's the most fun? Swapping faces with celebs yourself. Sure, you could just do it for fun. Or you could do it for the easiest, cheapest, digital Halloween costume ever. Sure, it's not something you can really wear out of the house — but hey, it will live forever on Instagram, right?

We decided to give it a shot ourselves and ended up with some pretty incredible results. And since we're in the Halloween spirit, we focused in on the Descendants and Riverdale cast and crew. There's nothing to get you in the spooky spirit like a little Disney magic or your favorite murder mystery CW show. Want to see how it turned out? Check out our gallery of face swaps below — then grab some pics of your favorite stars and characters and try it out for yourself.
