It happens every single year. You walk into a Spirit Halloween or scroll through TikTok in mid-October, and there they are. The red cap. The green cap. Those suspiciously thick, synthetic mustaches. Halloween Mario and Luigi setups are essentially the "Old Reliable" of the holiday. It doesn't matter if you're five years old or a thirty-something hitting a dive bar crawl; the brothers from Brooklyn are inevitable.
But why?
Nintendo has released dozens of characters since 1985. We have high-definition inklings, complex fire emblem heroes, and the cinematic grit of The Last of Us characters. Yet, the plumbing duo remains the undisputed heavyweight champion of the costume rack. Honestly, it’s partially due to the sheer accessibility. You don't need a 3D printer or professional foam-smithing skills to look like Mario. You just need primary colors and a dream.
The Evolution of the Mushroom Kingdom Look
Back in the 80s and early 90s, a Halloween Mario and Luigi costume was a nightmare of plastic. If you grew up then, you remember the "smock and mask" era. It was a flimsy vinyl apron with the character's face printed on your chest, topped with a brittle plastic mask that was held on by a single staple and a rubber band that always snapped. It smelled like a chemical factory. It was terrible.
Fast forward to today. The quality has shifted toward "cosplay-lite." People aren't just buying the bagged kits anymore. They're sourcing actual denim overalls from Carhartt or Dickies. They're buying high-quality newsboy caps. There is a weird sort of pride in making the plumber look "authentic."
Nintendo itself has leaned into this. Look at Super Mario Odyssey. The game literally featured a "Skeleton Suit" and a "Zombie Mario" outfit. This gave fans a "canonical" way to do a spooky Mario. Suddenly, you weren't just a plumber; you were an undead plumber. It added a layer of meta-humor that the DIY community absolutely latched onto.

Why the Dynamic Duo Works for Pairs
Luigi is the secret weapon of this trend.
If Mario is the icon, Luigi is the personality. For years, Luigi was just a "Green Mario," a palette swap for the second player. But games like Luigi’s Mansion changed the stakes. It gave Luigi a specific vibe: the "reluctant hero." He’s scared. He’s shaking. He’s relatable. When people go out as Halloween Mario and Luigi, the person playing Luigi usually gets to have more fun with the acting. They get to be the comic relief.
It’s the ultimate low-friction buddy costume.
- It works for brothers.
- It works for couples.
- It works for best friends who waited until October 30th to find a costume.
- It even works for parents and kids.
There is an inherent recognition factor here that few other franchises can touch. If you dress up as a specific character from Genshin Impact, you’re going to spend half the night explaining who you are. If you wear a green hat and overalls, everyone from your nephew to your grandmother knows exactly what’s going on.
The DIY vs. Store-Bought Debate
There’s a clear divide in how people approach Halloween Mario and Luigi gear. The "Bagged Costume" is the entry point. It’s convenient. You get the jumpsuit, the hat, and the mustache in one go for about $30.
But the enthusiasts? They go the "closet cosplay" route.
Actually, using real clothes makes the costume much more comfortable for a long night out. Polyester jumpsuits don't breathe. They’re static-electricity magnets. If you're heading to a crowded party, you're going to sweat. A pair of real cotton overalls and a breathable t-shirt is a massive upgrade. Plus, you can actually use the pockets. Have you ever tried to find a pocket in a cheap Halloween costume? They don't exist. You end up carrying your phone and keys in your hand all night like a loser.
Essential Components for the "Authentic" Look
- The Overalls: Blue denim is the standard, but the Super Smash Bros. versions often lean toward a darker, sturdier navy.
- The Mustache: Don't use the sticker ones that come in the pack. They fall off the moment you take a sip of a drink. Buy some spirit gum or a lace-backed theatrical mustache if you’re serious.
- The Gloves: White parade gloves. They feel weird, but they sell the silhouette.
- The Boots: Work boots, specifically rounded "bubble" toes, mimic the art style best.
The Luigi's Mansion Factor
We have to talk about the "spooky" version of these characters. Since Luigi's Mansion 3 on the Switch, the demand for "Ghostbuster Luigi" has skyrocketed. This is the perfect intersection of the theme. It’s a Halloween-themed game used for a Halloween costume.
Building a Poltergust G-00 out of cardboard and PVC pipe has become a rite of passage for DIY-heavy gamers. It moves the costume from "low effort" to "award-winning." It’s also a great way to incorporate props. People love props. A Poltergust gives you something to do with your hands and a place to hide a battery pack for LED lights.
Beyond the Basics: Wario and Waluigi
Sometimes, the primary colors are too boring. That’s where the "Anti-Mario" squad comes in. Wario and Waluigi have seen a massive surge in popularity over the last five years, largely driven by internet meme culture.
Waluigi, in particular, has become a cult icon. He’s lanky, he’s weird, and his "WAH" is a universal language. Dressing as the purple-clad villain allows for a much more chaotic energy at parties. While Halloween Mario and Luigi are wholesome and heroic, Waluigi is there to cause problems on purpose. It’s a different vibe entirely, often preferred by the college crowd or veteran gamers who want to subvert the expectation.

Real-World Impact and Global Appeal
Mario isn't just a video game character; he’s a cultural ambassador. According to various retail data from companies like Rubies II (one of the largest costume manufacturers), Nintendo-licensed products consistently rank in the top five every year. Even when a massive movie like Barbie or Spider-Man dominates the zeitgeist, Mario stays steady. He’s the "blue chip" stock of the costume world.
Interestingly, the release of The Super Mario Bros. Movie in 2023 gave the trend a massive second wind. It introduced a new generation to the "Plumbing Van" aesthetic. We started seeing more people carrying wrenches or tool belts as part of the ensemble. It added a layer of "blue-collar realism" to a world of talking mushrooms.
How to Make It Stand Out This Year
If you’re planning on doing the Halloween Mario and Luigi thing, don't just be "Guy in Hat."
Add some grit. Maybe you’re "Battle-Worn Mario." Use some fabric paint to add "soot" and "dirt" to your overalls. Rip the sleeves a little. Give yourself some fake bruises. It tells a story. You didn't just show up; you just survived World 8-4.

Another popular twist is the "Gender-Swap" or "Peach-and-Daisy-fied" versions. High-fashion takes on these characters—using sequins, tutus, or tailored suits—allow for creativity while keeping the core iconography intact.
Actionable Steps for a Better Costume
- Size Up the Hat: Most cheap Mario hats are tiny. They look like they're perched on top of your head. Find a "Big Style" hat that actually covers your crown; it looks much more like the game art.
- Fix the Mustache: If the adhesive is failing, use a tiny bit of eyelash glue. It’s skin-safe and holds up against sweat better than the factory tape.
- Prop Consistency: If you're Luigi, carry a flashlight. If you're Mario, a gold coin or a plastic plunger. It sounds cheesy, but it helps people "get" the character immediately.
- Coordinate the Group: If you have a third friend, don't let them be a random character. Force them into a Toad vest or a Peach dress. The visual impact of a group is exponentially higher than a solo plumber.
At the end of the day, the staying power of these characters comes down to joy. There’s no baggage with Mario. He’s not a controversial figure. He’s a guy who jumps on turtles to save a princess. When you put on that red or green hat, you’re signaling that you’re there to have a good time. It’s a costume that invites people to smile, and in a world where everything is increasingly complicated, being a simple Italian plumber for a night is a pretty great escape.
Next Steps for Your Halloween Planning:
Start by auditing your own closet for denim or canvas overalls before buying a pre-packaged kit. If you're going for the Luigi's Mansion look, source a vacuum hose early in September, as hardware stores often run low on specific diameters as DIY season peaks. Always test your mustache adhesive at least 24 hours before your event to check for skin sensitivity.
