Dr. Seuss created chaos. Pure, unadulterated, blue-haired chaos. When The Cat in the Hat first hit shelves in 1957, nobody expected two small, red-jumpsuit-wearing creatures to become the go-to aesthetic for every pair of best friends, siblings, or chaotic couples for the next seventy years. But here we are. Honestly, Thing One and Thing Two Halloween costumes are the ultimate fallback. They’re easy. They’re recognizable from a football field away. But they’re also really easy to mess up if you just buy the cheapest bag-set from a big-box retailer.
You've seen them. The ones where the wig looks like a matted sapphire Muppet and the jumpsuit is so thin it’s basically translucent. We can do better.
The Psychology Behind the Red Jumpsuit
Why does this work? It’s basically the "Low Effort, High Impact" rule of costuming. Unlike trying to explain a niche anime character or a political pun that requires a ten-minute monologue, everyone gets this. It’s universal. It’s nostalgic. It taps into that specific brand of childhood anarchy that Dr. Seuss (Theodor Geisel) mastered.
Interestingly, the original sketches by Geisel didn't have much detail. They were minimalist. That’s the secret. You have a blank canvas of red and white, topped with a shock of cyan. It’s a color palette that pops in photos, which is why it’s a staple for Instagram and Pinterest feeds every October. If you’re looking to stand out, you have to lean into the quality of the materials rather than the novelty of the characters.
How to Source Your Thing One and Thing Two Halloween Costumes
Most people just Google a kit. Don't do that. Or, if you do, be picky.

If you want to actually look good, you should consider the "Mix and Match" approach. Buy a high-quality red cotton union suit or a pair of solid red scrubs. Why scrubs? They have pockets. You’re going to want pockets for your phone and keys while you’re out causing "mischief."
The patches are the easy part. You can find iron-on "Thing 1" and "Thing 2" circles on Etsy or even make them with felt and a Sharpie if you’re feeling crafty. The DIY route usually looks more "authentic" than the shiny, polyester sheen of a $20 pre-packaged bag costume.
The Hair Problem
The wig is usually where these costumes go to die. Cheap synthetic wigs itch. They shed. They look like a blue bird’s nest after twenty minutes of sweating in a crowded room.
- Option A: The High-End Synthetic. Look for "heat-resistant" fibers. They have less of that plastic shine.
- Option B: Hair Chalk or Spray. If you have short hair, just dye it temporarily. It looks way more natural and less like a hat.
- Option C: The Tulle Headband. For kids (or adults who hate wigs), a headband with vertical strips of blue tulle gives the vibe of the hair without the sensory nightmare of a full wig.
Variations for the Modern Era
It isn't just for duos anymore. Groups have started expanding the "Thing" universe. I’ve seen families go up to Thing 4, Thing 5, and even a "Mother of All Things" shirt for the parent. It’s a bit cliché, sure, but for a family of five trying to get out the door by 6:00 PM on Halloween night? It’s a lifesaver.

For couples, there’s the "Cat in the Hat and a Thing" dynamic. It’s a bit more hierarchical, but it works. If you're going as a couple, please, for the love of all things holy, make sure your reds match. Nothing ruins the aesthetic faster than one person in a maroon jumpsuit and the other in neon scarlet. It’s jarring. It’s wrong.
The "Adult" Twist
Let’s be real: some people want to make this "sexy." It happens to every costume. A red corset, red tutu, and blue fishnets. Is it Seuss-approved? Probably not. Does it work at a Vegas club? Absolutely. The key here is the "Thing" circle. As long as that white circle is visible on the chest or stomach, the costume is anchored. Without it, you’re just a person in red who forgot their wig.
Common Mistakes and How to Avoid Them
The biggest mistake is ignoring the shoes. People spend forty dollars on a jumpsuit and then wear their dirty, lime-green running shoes. It kills the silhouette. Wear red shoes, white shoes, or even black boots. Just don't wear something that clashes with the primary colors.
Another thing? The makeup. You don't need a full face of white paint. This isn't a clown costume. Keep it simple. Maybe some blue eyeliner to match the hair, or a red lip. If you go full face-paint, you’re going to be smeared and miserable by 10:00 PM.

Why This Costume Still Matters in 2026
We live in a world of complex, multi-layered pop culture references. Sometimes, you just want to be a "Thing." There is a certain freedom in putting on a costume that represents pure, mindless fun. You don't have to stay in character. You don't have to do an accent. You just have to be a little bit chaotic.
Also, from a practical standpoint, these costumes are warm. Halloween in most of the northern hemisphere is freezing. A full-body red jumpsuit allows you to layer thermal underwear underneath without anyone being the wiser. It’s the pragmatic choice for the cold-natured reveler.
Actionable Tips for Your Best Seuss Look
- Check the "Thing" Circle Placement. It should be centered on the sternum, not the belly. If it’s too low, it looks like a belt. Too high, and it gets lost under your chin.
- Texture is Your Friend. Mix a fuzzy blue wig with a matte cotton jumpsuit. The contrast makes the costume look intentional and "designed" rather than "bought."
- The "Prop" Factor. Carry a kite. Or a "Box." In the book, the Things come out of a decorative crate. A small cardboard box spray-painted red with "Things" written on it can function as a quirky handbag for the night.
- Group Coordination. If you're doing this with a friend, decide who is "One" and who is "Two" before you buy the patches. You don't want two "Thing Ones" walking into the party. It ruins the bit.
- Wash Your Jumpsuit First. Cheap red fabric is notorious for bleeding dye. If you get caught in a Halloween rain shower, you don't want to end up looking like a pink version of the Incredible Hulk.
When you're choosing your Thing One and Thing Two Halloween costumes, focus on the fit and the hair. Get those two things right, and the rest is easy. Whether you're chasing kids around a neighborhood or heading to a house party, the goal is the same: look like you're about to knock over a lamp and have a blast doing it.
Start by looking for a base layer that is 100% cotton for breathability. Then, hunt down a wig that has a mesh cap—it’ll save your scalp from the inevitable itch. Finally, grab a friend who is willing to be the "Two" to your "One" and keep the chaos contained to the dance floor.
