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.
This is an awesome Star Wars t-shirt featuring a realistic Boba Fett print sublimated across the entire front and back of the top. The true all-over print makes a great costume starter. This would match well with light grey or tan pants you probably already have in your closet.
Dress like an X-Wing pilot with this fun printed orange t-shirt. It's got the gear and hoses worn by pilots printed right there on the shirt. This would look great with orange pants if you've got them, and a white motorcycle helmet.
