If you happen to have a friend who is dressing up as Mario this Halloween, why not go as a pair and dress up in a Super Mario Bros Luigi costume? For this costume, just be sure to wear a long sleeved green shirt and a matching green hat to go along with it. Make sure that the hat has a small green “L” on the front of it–just like how it is in the video game. You can wear whatever shoes you’d like with this Luigi costume. Just be sure to wear some dark colored shoes (preferably brown though).
