Mischief? Mayhem? This Onesie Says Yes!
Some people enjoy a quiet night in. Others prefer absolute, unhinged mayhem. If you fall into the second category, congratulations—you're officially Thing material! With this officially licensed Thing 1 & 2 Costume Onesie, you can embrace the wacky, whirlwind energy of Dr. Seuss's most iconic troublemakers.
This Made By Us outfit is perfect for running through the house like a human tornado or just looking for the comfiest way to channel your inner mischief-maker. This onesie has got you covered with a completely comfortable, pajama-style fit.
Design & Details
Designed for maximum comfort (and maximum silliness), this kigurumi-style jumpsuit is made from ultra-soft 100% polyester fabric, so it feels just like pajamas. The loose fit makes it perfect for running, jumping, or dramatically flopping onto the couch after a long day of Seussian shenanigans. The bright red suit features light blue rib-knit cuffs, and the hood is topped with soft, fluffy faux fur to give you that signature wild Thing hair.
But the best part? It comes with interchangeable patches, so you can decide whether you're Thing 1 or Thing 2—or switch throughout the night just to keep people on their toes! The front fastens for easy wear, making it simple to slip into costume mode whenever the urge for fun strikes or whenever The Cat in the Hat decides to call you up for some wacky fun!
Ready to Run Amok
Whether you're planning a Dr. Seuss-themed event, a cozy costume party, or just feel like causing some (harmless) chaos, this Thing 1 & 2 Costume Onesie is ready for action. Just remember: with great mischief comes great responsibility… and maybe a little clean-up afterward, so make sure you bring another Thing along for the ride. After all, antics (and cleanup) is always more fun with a friend.
