If you love the Star Wars universe and want to get dressed up as a favorite character, it's easy to do with novelty printed tops. You can go as a Wookiee or a Droid without wearing a big fur suit or designing a molded robot costume. These work great as a group costume idea too, because of their affordability and variety of available sizes. It's easy to have multiples of several costumes, too, like the Stormtroopers, X-Wing Pilots, and Ewoks. Here are some easy Star Wars t-shirt-based and tank-based costume ideas for Halloween.
