Onesie or Suit: Choose Your Costume Format
Not sure which format to pick? A onesie, like Charmander or Cookie Monster, is the most immersive option, ideal for a Halloween party or trick-or-treating where comfort matters. A suit version, like Pokémon or Superman™, gives you the same character without sacrificing a more put-together look, useful if your Halloween event doubles as an office party or a night out.
Looking for a specific format? Browse Halloween Onesies, Halloween Suits for Men, or the wider Halloween Outfits collection. There's also Halloween suits for kids and for teens.
Frequently asked questions about Halloween costumes
What's the difference between the onesie and suit Halloween costumes?
A onesie is a single, all-in-one costume piece for a bold, full-character look, while a suit version reworks the same character into a wearable jacket-and-pants set, better suited to events with a bit more of a dress code.
Are the character costumes officially licensed?
Yes, many designs are officially licensed, including Pokémon, DC Comics, Sesame Street™, Sonic the Hedgehog™, South Park™, Super Mario™, and Minecraft™.
Are there Halloween costumes for kids and teens too?
Yes, alongside the men's and women's sizes, there are Halloween suits and onesies sized for kids and teens.
Can I put together a group costume?
Yes, the collection includes built-in group sets, such as all four South Park™ friends (Stan, Cartman, Kyle, and Kenny) as matching onesies, or Bert™ and Ernie™ as a Sesame Street™ sweater pair.
When will my Halloween costume arrive?
