Max from the Grinch Costumes

The Grinch may have had a heart two sizes too small, but Max the dog? Max had heart to spare. Loyal, patient, and always down for a sleigh ride (even when the sleigh was clearly too heavy and morally questionable), Max is the unsung hero of Whoville. He saw the good in the Grinch long before anyone else did, and that kind of unwavering support deserves celebration. That’s why our Max from the Grinch costumes are designed to capture every bit of his sweet, scrappy charm—from his floppy ears to his sleigh-pulling spirit.

For grown-ups who want to embrace their inner good boy, we’ve got cozy adult Max jumpsuits that’ll make you the most adorable accomplice at any holiday gathering. And don’t worry—we didn’t forget the tiniest Whos. Our toddler and infant Max costumes are perfect for making mischief look extra cute, and we offer kid-sized Max suits too, because loyalty knows no age limit. We even carry plus size options, so everyone can get in on the heartwarming holiday fun.

Need something that’s comfy and festive? Try slipping into a pair of our Max character slippers—they’re soft, warm, and feature that unmistakable Max face that says, “Sure, I’ll pull your sleigh… again.” Want a quick and easy transformation? Our Max Grinch headband is a no-fuss way to channel your inner Christmas canine. And yes, we went full meta: we even have Max Dog Grinch Costume options so your real dog can dress up as Max dressed as a reindeer. That’s layers of loyalty right there.

Every Max look in our collection is officially licensed and lovingly crafted by our in-house design team, so you're not just getting holiday gear—you’re getting pieces made with genuine Grinch-level attention to detail (but in a good way). From headbands to full jumpsuits, we’ve got the look for you, your kiddo, and even your four-legged sidekick.
