You know the song. You’re probably humming it right now. "Bananas in pajamas are coming down the stairs..." It’s a rhythmic earworm that has lived rent-free in our collective subconscious since 1992. But here is the thing: the bananas in pajamas outfit isn't just a relic of Australian public broadcasting or a nostalgic 90s memory. It has transformed into a legitimate cultural phenomenon that pops up at every music festival, stag do, and Halloween party from Sydney to London.
Honestly, it’s a bit weird if you think about it. We are talking about two giant, sentient fruits wearing blue-and-white striped sleepwear. Yet, the costume remains a top-tier choice for duos who want to be recognizable without having to put in an ounce of effort into "acting" like a character. You just stand there. You're a banana. People get it.
The Anatomy of a B1 and B2 Look
If you're looking to source a bananas in pajamas outfit, you have to decide if you're going for the "prestige" mascot look or the "budget-friendly" DIY version. Most store-bought versions are basically giant foam tunics. They’ve got that signature curved top—the "stalk"—and a mesh screen over the mouth or eyes so you don't walk into a wall. The real kicker is the collar. It has to be that specific, crisp white 90s-style lapel.
What most people get wrong is the scale. B1 and B2 were huge. If your pajamas are too tight, you just look like a guy in stripes. You need that boxy, oversized silhouette.
Think about the material for a second. Most cheap polyester costumes are heat traps. If you're wearing one of these to a summer festival like Glastonbury or Splendour in the Grass, you are essentially steaming yourself inside a yellow fruit casing. Professional cosplayers or high-end prop makers often use breathable foam or even lightweight wire frames to keep the "peel" from collapsing.
Why the Stripes Matter So Much
The blue and white stripes aren't just a design choice; they’re the identity. In the original ABC (Australian Broadcasting Corporation) series, the pajamas were actually quite heavy-duty fabric. They had to withstand the actors—originally Duncan Wass (B1) and Ken Radley (B2)—moving around and "chasing" the Teddies.
If you are DIY-ing this, don't just buy any striped PJs. You need the vertical orientation. Horizontal stripes make you look like a 1920s prisoner who happens to have a yellow head. Not the vibe. You want the classic "hospitality stripe" look.

Why is this still a thing? Well, it’s the ultimate "low-stakes" costume. You don't need to do a voice. You don't need a backstory. You just need a friend who is roughly your height.
ABC’s Bananas in Pyjamas (yes, that’s the Aussie spelling) was inspired by a 1967 song by Carey Blyton. When it hit TV screens in the early 90s, it took over the world. It was syndicated in over 70 countries. That is a massive footprint. It means that whether you grew up in the US, the UK, or Australia, you have a baseline understanding of what these characters are.
Cultural critics often point to the "Twin Factor." Psychologically, there is something inherently funny about two people dressed exactly the same. It creates an instant visual gag. When you see a bananas in pajamas outfit in the wild, it's rarely just one. It’s always B1 and B2.
The Great Animation Shift
In 2011, the show moved to CGI. Purists hated it. The "real" Bananas were guys in suits. There was a tactile, slightly clunky charm to the original costumes that the 3D models just couldn't replicate. This is why the most popular versions of the outfit today still mimic the 1992 live-action aesthetic. We want the felt. We want the slightly awkward, oversized heads.
Spotting a High-Quality Costume vs. a Knockoff
Let’s be real: some of the versions you find on late-night internet deep dives are terrifying. If the yellow is too neon, you look like a highlighter. If the "face" is printed on the chest instead of being a separate headpiece, it loses the magic.
- The Headpiece: It should be structured. A floppy banana top is a sad banana top.
- The Fabric: Look for brushed poly-foam. It holds the shape without being as heavy as real upholstery foam.
- The Numbers: You must have the B1 and B2 on the collars. Without the numbers, you're just a generic fruit in bed.
- The Footwear: The original characters wore oversized yellow "shoes" that looked like part of their peel. Most costumes skip this, but if you want to win a contest, yellow slip-ons are mandatory.
Making the Outfit Work for Groups
While B1 and B2 are the stars, the "Bananas universe" allows for some pretty easy group expansions. You’ve got the Teddies—Amy, Lulu, and Morgan. Then there’s Rat in a Hat.

Rat in a Hat is the unsung hero of 90s costume design. A checkered waistcoat, a straw boater hat, and a bow tie. If you have a group of six, you have a full cast. The contrast between the bright yellow bananas and the slightly "used car salesman" aesthetic of the Rat is comedy gold.
Honestly, the Rat costume is way more comfortable. You aren't wearing a five-pound foam head. You just have some ears and a tail. But you won't get the same "Hey! It's the Bananas!" reaction from across the bar.
The Practicalities of Wearing a Giant Banana
Listen, nobody tells you about the logistics. Wearing a bananas in pajamas outfit is a commitment.
- Hydration: You will sweat. A lot. Most of these suits are 100% synthetic.
- Navigation: Peripheral vision? Forget about it. You’re looking through a tiny mesh slit. You need a "handler" or at least a B2 who can see slightly better than you.
- The Bathroom Situation: This is the big one. Most of these are one-piece jumpsuits or have complicated velcro backs. Don't wait until the last minute.
Despite the heat and the lack of vision, people keep buying them. According to retail data from major costume hubs, "90s Nostalgia" is a top-three category every single year. The Bananas consistently rank alongside the Power Rangers and Mario as the most searched duo costumes.
How to Style Your Own Version
If you want to avoid the "baggy yellow sack" look, try a "Fashion Banana" approach.
Find a high-quality pair of blue and white striped pajamas. They make these in silk or heavy cotton now. Then, instead of a full foam suit, just get a high-quality banana headpiece. It’s more breathable, looks "ironic" rather than "cheap," and you can actually sit down at a table to eat.

For a more "streetwear" take, some people are even doing custom embroidery. Imagine a B1 patch on a designer pajama set. It’s subtle. It’s "if you know, you know."
The Crossover Appeal
We’re seeing these outfits show up in weird places. Professional wrestlers have worn them for "comedy matches." TikTokers use them for "coming down the stairs" pranks that get millions of views. It’s a visual shorthand for "we’re here to have a ridiculous time."
There is also a weirdly large market for dog versions of this costume. Yes, you can buy a bananas in pajamas outfit for your French Bulldog. It usually just consists of the striped shirt and a little yellow hat, but it’s undeniably effective.
What to Do Before You Buy
Don't just click the first link on an auction site. Check the height requirements. Most of these are "one size fits most," which usually means "if you are over 6'2", your ankles are going to show, and if you are under 5'4", you're going to trip over the peel."
Read the reviews specifically for the "top-heavy" issue. Some cheaper headpieces don't have internal straps, so every time you nod your head, the banana flops over like a wilted vegetable. You want one with a chin strap or an internal foam "hat" that keeps it secure.
Your Banana Action Plan
If you’re ready to embrace your inner B1 or B2, here is how to execute it perfectly:
- Coordinate with your partner: Ensure you both have the same "style" of costume. A high-def mascot next to a DIY pajama version looks messy.
- Check the stripes: Ensure they are vertical and the blue is a true royal blue, not navy.
- Prioritize the "B" embroidery: If the costume doesn't have the B1/B2 insignias, buy some white felt and a Sharpie and make them yourself. It’s the detail that makes the character.
- Plan your exit: Since these costumes are bulky, make sure you have a way to transport them to the venue. You aren't fitting into a compact car while wearing a four-foot yellow foam head.
The bananas in pajamas outfit succeeds because it's wholesome, hilarious, and deeply rooted in a time when TV felt simpler. Whether you’re doing it for the "likes" or just to make your friends laugh at a house party, it’s a guaranteed win. Just remember: B1 always goes first. It's the law of the stairs.
