Dr. Seuss Thing 1 & 2 Adult Costume Onesie

When Comfort Meets Chaos

If there’s one thing we know about Thing 1 and Thing 2, it's that they never do anything halfway. They don't just walk—they zoom. They don't just play—they wreak joyful havoc. And now, you can embrace that same energy with this officially licensed Thing 1 & 2 Costume Onesie! Whether you're planning a Dr. Seuss-inspired event, heading to a costume party, or just want to add a little extra fun to your loungewear lineup, this onesie is ready to bring the mischief (in maximum comfort, of course).

Fun Details

This ultra-soft jumpsuit feels just as cozy as pajamas, making it perfect for running wild or curling up with a good book after a long day of antics. The bright red design captures the classic look of Thing 1 and Thing 2, complete with light blue rib-knit cuffs for a snug, comfy fit. The hood is covered in soft faux fur, recreating that instantly recognizable, slightly wild hairdo that makes Things so distinct.

You get to choose your Thing status! The onesie includes interchangeable "1" and "2" patches that attach to the front, so you can switch between roles whenever the mood strikes. A row of front fasteners makes it easy to slip on and off, while the loose fit keeps movement easy—because let's be honest, standing still isn't exactly a Thing specialty.

Playful Pandemonium

Comfortable enough for all-day wear and whimsical enough to steal the spotlight in any story, it's the perfect way to bring a little storybook magic to any occasion. Just be prepared—once you put it on, you're almost obligated to engage in some mischief around the house. And this time... the Cat in the Hat might not be around to help you with the clean-up.
