Maximum Mischief, Mini Size

There's chaos, and then there's "just discovered how to crawl at top speed" chaos—and that's where the Dr. Seuss Thing 1 & 2 Infant Costume fits right in. This pint-sized red jumpsuit channels the pure, unfiltered energy of the Cat in the Hat's most lovable little troublemakers. Whether your tiny tornado is playing the part of Thing 1 or Thing 2 (you get to choose!), this outfit makes every squiggle and squeal Seuss-level adorable.

This costume's got big personality packed into a small bundle. It's for babies who are ready to turn story time into a full-scale production—and maybe take down a few blocks and snack containers in the process. It's also perfect for parents who like to lean into the fun, unpredictable joy of raising a certified cutie with cartoon-level energy.

Design & Details

The costume includes a red jumpsuit, a fuzzy blue hat, and felt numbers 1 and 2 that you can swap out with a hook-and-loop fastener. The jumpsuit is made from 100% polyester, and the hat blends 59% polyester with 41% acrylic, lined in fleece for extra coziness. It has snaps along the inseams for easy diaper access (because babies will pick the worst times for a change), and the jumpsuit pulls over the head like a shirt.

Hand covers flip back when you need fingers free and fast. The appliquéd "THING" circle on the chest is embroidered, so it won't peel off mid-snuggle. And yes, it's officially licensed and exclusively made by us, so you're getting top-tier Seussian style. Just a heads-up: this costume includes the numbers 1 and 2—if you want a twin set, you'll need a second costume to have 2 suits!

One Little Thing, Infinite Laughs

Babies in costume are already the MVPs of Halloween, but dress one up as a beloved Seuss character and you unlock a whole new level of cute. This is the costume that turns stroller rides into parades and nap times into backstage dressing room drama. And if there's a sibling, cousin, or baby bestie involved? Double the Things, double the fun.
