Do you have a best bud? Maybe he’s that guy who’s right at your side at the bars, or maybe he’s that dude always laying around on your couch mooching food. Maybe he’s that guy who’s always pulling you out of a tight situation, or perhaps he’s the one who drags you into bad situations in the first place. Either way, he’s got your back no matter what. If your looking to pair costumes, whether they be strange, quirky, funny and sometimes even dorky—this guide is dedicated to famous best bud costumes!
Hall and OatEs: Daryl Hall and John Oates COSTUMES
Hall and Oates go together like, well, Hall and Oates! These guys are one of the longest lasting musical duos in the music business and even hardcore music snobs have a hard time trying to hate on these two. Of course, the best part about Hall and Oates is the very fact that they’ve been making hits since the 70s, so they’ve incorporated 70s and 80s style into their look at some point in their career. If you're looking for best duo costumes for guys, a Hall and Oates costume makes for a great pair.

Mushroom Kingdom would probably have problems tying its metaphorical shoe laces if not for this pair of plumber brothers. Since the 1980s, the brother duo has been teaming up to save princesses, stomp on koopas and win go-kart races, which makes one ponder the question of when they actually get around to doing any plumbing work. Nintendo has made this classic duo a cinch. This pair of dynamic duo costumes will certainly be fun and comfortable all night long!

No matter what challenge the bad guys throw at these guys, they have just the series of punches and kicks that will take them out. But all of this is just beating around the bush. The REAL reason any two guys need to make this duo costume happen is the look on people’s faces when you shout, “HADOUKEN!” in unison. Just make sure Chun Li doesn’t show up. Old Thunder Thighs has the womanly wiles that can tear two good buds apart.

The brash Lion-O led the team, but Panthro acted as the wise older brother figure to the group, and the duo tussled with everything from mechanized Viking berserkers, to evil mutants. What more could best buds want than to spend their time facing off against a magical mummy who wants to steal your Eye of Thundera?
