Super Mario Bros Costume Ideas in 2026

Super Mario Bros costumes are some of the most recognizable, simplest builds on this entire site: a red or green cap, overalls, and a mustache cover Mario or Luigi almost entirely. Nearly anyone can assemble this from a hardware-store hat and basic clothing.

The franchise has decades of games plus a recent hit film behind it, reaching essentially every age group. Few costumes on the site carry less risk of going unrecognized than this one, it's about as safe a pick as they come.

The color is the only real variable, red for Mario, green for Luigi, everything else about the build stays the same, so pick your color and don't overthink the rest.

Mario and Luigi are the definitive duo, and honestly one of the easiest, most recognizable pairs on the entire site. For a bigger group, add Princess Peach and Toad, the bright, simple color-blocked designs across the whole cast make for an easy, colorful group costume.
