If your child is into gaming and especially Nintendo, then this Super Mario Bros Mario costume for toddlers could be just the right thing for them to wear this Halloween. Not only is it easy to put together on your own but very recognizable as well. If you plan on putting this outfit together yourself, make sure to wear a red long-sleeved shirt and some dark blue overalls. You’ll also need a red Mario hat with the small “M” on the front of it. Wear a fake moustache over your upper lip and some brown shoes and you’re all set!
