Maxed-Out Holiday Mischief meets cozy comfort with the Plus Size Grinch Adult Costume Onesie. If you love Christmas with a side of sarcasm, this officially licensed jumpsuit is your new holiday uniform—soft, fuzzy, and perfectly grumpy for parties, movie nights, or epic couch marathons with cocoa.

Designed for big green energy, this onesie is made from 100% polyester stretch sherpa faux fur for a warm, plush feel. A front zipper makes outfit changes a breeze between plotting gift theft and lounging, while rib-knit cuffs at the wrists and ankles keep the fit snug and prevent ride-up. The hood features embroidered Grinch facial features and a tuft of fuzzy yellow hair for that classic mean-mug moment, with a smooth poly knit lining inside for comfort. Over the heart, a bright red embroidered symbol adds a nod to the Grinch’s three-size moment when dessert is served.

Fuzzy, festive, and a little unhinged, this unisex plus-size costume is perfect for holiday parties, movie nights, or simply skipping the mall in favor of hot chocolate and witty gift wrapping. Embrace your inner Grinch and bring bright greens, big personality, and cozy energy to the season.
