Few horror villains land harder at a Halloween party than a grinning alien straight off the Big Top. Killer Klowns from Outer Space has been building a cult following since 1988, and the costume options have finally caught up with the fandom. We pulled together the best Killer Klowns from Outer Space costumes available right now — full character looks, screen-accurate masks, and the pieces to build your own Klown.
Key Takeaways
- 4 Klowns are available as complete officially licensed costumes — Jumbo, Slim, Shorty, and Spikey — in both adult and child sizing
- Every full costume includes the same 3 pieces: jumpsuit, collar, and mask, so nothing extra is required to get the look
- Masks come in 3 quality tiers, from budget one-size options to premium latex sculpts built for collectors
- Characters without a full costume, including Rudy and Jojo the Klownzilla, can still be assembled using a standalone mask plus your own base pieces

What Comes With a Killer Klowns Costume?
Every full costume in the lineup ships with the same 3 components — a jumpsuit, a collar, and a mask. That matters, because a lot of horror costumes leave you hunting for the headpiece separately. Here, the character is complete in one box.
What is not included: shoes, gloves, and any props shown in product photography. Styling items pictured alongside the costume are not part of the purchase.
Sizing runs small through extra-large on both the adult and child versions, and each costume is hand wash or spot clean only. These are officially licensed designs, not generic circus outfits — the color blocking, collar shape, and facial sculpt all track the characters as they appeared on screen.
Costume demand backs up the timing. The National Retail Federation expects Halloween spending to reach $13.5 billion, with roughly $4.4 billion of that going to costumes alone and half of all consumers planning to dress up.
The Complete Killer Klowns Costume Lineup
Jumbo
The first Klown to step off the Big Top and the largest of the bunch, Jumbo is the natural pick for anyone who wants instant recognition. The Jumbo adult costume pairs a purple-toned jumpsuit with the oversized collar and a mask that captures his heavy brow and jagged grin. There is a matching Jumbo child costume if a smaller Klown is joining the invasion.
Slim
Slim is the lanky one with the frizzy orange hair and the pink jumpsuit trimmed in blue — the Klown most people picture when they think of the Klown Parade. The Slim adult costume runs through all 4 adult sizes, and the Slim child costume carries the same color treatment down to the collar.
Shorty
Small frame, bad attitude. The Shorty adult costume delivers the yellow-forward look and the stubby, sneering face that makes Shorty such a fan favorite. The Shorty child costume is the closest thing to a scaled-down version of the character available.
Spikey
The green-haired Klown with the aggressive silhouette rounds out the set. The Spikey adult costume is a strong choice for group looks because it reads differently from the other 3 at a glance. The Spikey child costume is offered in small, medium, and extra-large — large is not currently available, so check sizing before committing.
Put all 4 together and you have a full Klown Parade, which is exactly the kind of group costume that earns a room.
Which Killer Klowns Mask Should You Choose?
The mask is where the budget decision really happens. There are 3 distinct tiers.
Premium latex. These are the collector-grade pieces. The Shorty premium mask and the Slim full head mask are both built from high-quality latex, cover the head and neck, and were developed from screen reference. The Fatso full head mask is the only way to get Fatso as a wearable right now. Each is sculpted around an average head diameter of approximately 22 to 23 inches, with the finished masks measuring approximately 24 inches. They are made to order by hand, so slight variation in color and hair placement is normal rather than a flaw. Expect these to sit in the $80 to $125 range.
Deluxe injection. A rigid plastic build with an elastic strap and fur hair detail, painted to match the character. This tier covers Slim, Shorty, and — importantly — Rudy, who has no full costume. These generally land in the $50 to $65 range and are the sweet spot for most people.
Budget. The Shorty one-size mask and the Slim one-size mask both come in around $30 with a strap closure. If you already own the costume and want a backup, or you are building a look on a tight budget, start here.
Then there is the outlier: the Klownzilla latex mask. This overhead latex piece is the only way to go as Jojo, the towering Klown from the finale, and it is sized for older teens and adults.
How Do You Build a Killer Klowns Costume From Scratch?
Not every Klown has a boxed costume, and some fans would rather assemble something with more presence anyway. The approach is straightforward.
Start with the mask. Pick your character from the tiers above. This is the piece doing all the identification work, so put the budget here first.
Build the jumpsuit. The Klowns wear loose, brightly colored one-piece suits with contrasting trim. A solid-color coverall in the right shade — purple for Jumbo, pink for Slim, yellow for Shorty, green for Spikey — gets you most of the way. Rudy calls for bold vertical stripes.
Add the collar. A ruffled clown collar is the single detail that separates a Klown from a generic clown. Oversized and in a contrasting color is the goal.
Finish with scale. Oversized shoes and gloves exaggerate the proportions the way the characters do on screen.
Carry a prop. The 24-inch Popcorn Bazooka electronic prop replica is the standout here — the trigger drives light and sound, and a side handle rotates a popping mechanism behind a clear dome. For something lighter to carry all night, the orange plush baseball bat measures approximately 30 inches and the blue plush bat approximately 20 inches. Both are soft, safe for crowded parties, and instantly readable.
Frequently Asked Questions
Are Killer Klowns costumes officially licensed?
Yes. Every full costume and every mask in the main lineup is officially licensed, which is why the facial sculpts and color schemes match the film rather than approximating it. Licensed construction also means the sizing charts and care guidance are consistent across the range.
What sizes do Killer Klowns costumes come in?
Adult costumes run small through extra-large. Child costumes run small through extra-large as well, with one exception — the Spikey child costume currently skips large. Masks are generally one size fits most teens and adults, built around an average head diameter of approximately 22 to 23 inches.
Is there a Rudy or Fatso costume?
Not as a complete boxed costume. Rudy is available as a deluxe injection mask and Fatso as a premium latex mask, so both characters are achievable by pairing the mask with your own jumpsuit and collar. That is the build-your-own route described above.
How do you care for a Killer Klowns costume?
Hand wash or spot clean only. Work gently on the areas that need attention rather than putting the whole piece through a machine. Latex masks should be stored stuffed and out of direct sunlight to hold their shape.
What is the best Killer Klowns costume for a group?
Running Jumbo, Slim, Shorty, and Spikey together gives you 4 visually distinct Klowns who read as a unit — the Klown Parade effect. Adding a Rudy or Klownzilla mask build extends the group to 5 or 6 without repeating a silhouette.
Conclusion
The Klowns went from a hard-to-find cult license to one of the deepest horror costume lines around, and the Killer Klowns from Outer Space costumes available now cover everything from a complete one-box character to a fully custom build. 4 full costumes, 3 mask tiers, and a handful of props mean there is a version of this look at nearly every budget. Stack a few pieces together and Buy More, Save More does the rest.
