If you thoroughly enjoyed Waluigi’s character in the game, then you’ll definitely like wearing this Super Mario Bros Waluigi costume. This costume is also very easy to put together on your own. Wear a royal purple long sleeved shirt along with a royal purple hat with the upside down yellow “L” on the front. As for the moustache, you can either cut it out of paper or felt and attach it to your face in the right place. Wear some dark colored overalls and some brown shoes and you’re all done with your Waluigi costume! You can even add an accessory to your costume – like the rose in this picture.
