Let’s be honest. If you grew up in the 90s, you didn't just watch Hey Arnold!; you lived in that gritty, jazz-infused version of Brooklyn. And when Halloween or a 90s throwback party rolls around, the hey arnold and gerald costume is the ultimate power move. It’s the gold standard of "cool but nostalgic" duos.
But here’s the thing: most people mess it up.
They buy a cheap, itchy polyester sack from a pop-up shop and call it a day. Or worse, they wear a kilt for Arnold. Look, Craig Bartlett, the show’s creator, has cleared this up a thousand times—it’s not a skirt. It’s an oversized flannel shirt worn under a sweater. If you want to actually look like the "Keeper of the Tales" and the "Football Head," you need to get the layers and the architecture right.
The Arnold Shortman Blueprint: It’s All About the Layers
Arnold’s look is basically Seattle grunge meets 4th-grade prep. Bartlett actually based the outfit on how he dressed in the Pacific Northwest—lots of layers because it was always drizzly and cold.

To pull off a high-quality Arnold, you need a blue sweater. Not a sweatshirt. A knit sweater. Underneath that, you need a long, red-and-black (or orange-and-black depending on the season’s lighting) plaid flannel shirt. The tails of the flannel have to stick out significantly from the bottom of the sweater. This is what creates that "kilt" illusion.
- The Head Shape: This is the hardest part. You can buy a vinyl mask, but they’re often sweaty and weirdly proportioned. If you’re going for a more "human" version, just style your hair with some heavy-duty pomade or Got2b Glued spray to get those two distinct tufts on the side.
- The Tiny Hat: It’s a blue cap. It sits right in the middle. It’s ridiculously small. Don’t wear a full-sized beanie; find a doll-sized one or use felt to craft a miniature version that pins into your hair.
- The Bottoms: Simple blue jeans and black sneakers. Nothing flashy. Arnold is the moral compass; he doesn't need hypebeast kicks.
Getting the Gerald Johanssen "Tall Hair" Right
Gerald is the undisputed king of P.S. 118. He’s got the swagger, the urban legends, and the most gravity-defying hair in animation history. If you’re doing a hey arnold and gerald costume, the Gerald half is usually the one that catches everyone's eye because of the silhouette.
Most people think Gerald’s hair is a hat. It’s not. In the episode "Heat," we actually see his hair droop down when it gets wet—it’s just extremely tall, styled hair.

For the costume, you have two real options. You can buy the "official" tall wig, which often looks like a black velvet tube, or you can DIY it. If you’re DIYing, use a base of upholstery foam or even a tall Pringles can (emptied and cleaned!) covered in black faux fur or a textured afro wig. It needs to look like a cylinder, not a sphere.
The shirt is the easiest part. It’s a red long-sleeve jersey with a white "33" on the front. Fun fact: The "33" is a nod to Scottie Pippen, who wore that number for the Chicago Bulls during the show's peak. Wear it with blue shorts and red high-top sneakers. Converse All-Stars are the "lore-accurate" choice here.
Why the Details Actually Matter
If you just wear a red shirt and a blue sweater, you’re just two guys at a bar. The magic of a hey arnold and gerald costume is in the "lived-in" feel.

Gerald often wears a single small gold stud earring in his left ear. It’s a tiny detail, but it’s 100% Gerald. And Arnold? He needs to look slightly disheveled but kind. If you’re carrying a prop, skip the football. Carry a vintage-style "Cool" tape recorder or a small pig (Abner).
Pro-Tips for the Duo
- Height Check: In the show, Gerald is noticeably taller than Arnold, mostly due to the hair. If the person playing Arnold is taller, have them slouch or have the Gerald player wear lifts. It sounds extra, but it makes the photos look way better.
- The Palette: The colors in the show are muted and slightly "dirty" to reflect the city vibe. Don't go for neon red or electric blue. Look for "brick red" and "navy."
- The Attitude: Arnold is the "bold kid" who helps everyone. Gerald is the storyteller. If someone asks who you are, Gerald should be the one explaining the "Legend of Stoop Kid" while Arnold just nods empathetically.
Making It Reality
If you’re ready to put this together, don't wait until October 30th. Start hitting up thrift stores for that specific blue sweater and the perfect oversized flannel. For Gerald’s shirt, you can easily find "33" jerseys on sites like Etsy or even Target’s nostalgic collection, but make sure the red matches your sneakers.
The best part about this costume is that it’s actually comfortable. You’re basically wearing jeans, a sweater, and a jersey. You can stay in character all night without feeling like you’re trapped in a giant inflatable dinosaur.
Stick to the layers, get the hair height right, and remember: it's a shirt, not a kilt.
Next Step: Check your local thrift shop for a 100% cotton blue crewneck sweater; the texture is much more "90s" than modern synthetic blends.
