Are you a Monsters Inc fan? Is Mike Wazowski the only monster you weren’t scared of? Well, that’s great news because what we have here is a Mike Wazowski Onesie. Mike might be a bit rough around the edges, but in the end, he is the good guy. Hence, it’s no wonder this is one of the most popular onesies. It’s green and soft, yet the details on it are incredibly complex. Not only will you look just like Mike, but you might even actually scare someone while walking down the street! And, let’s not forget - if you get your partner to dress up as Sulley, you’ll be the most popular couple at the costume party!
