Get ready to own the trash can attitude with the Adult Plus Size Oscar the Grouch Costume Onesie. Officially licensed by Sesame Street, this cozy jumpsuit lets you channel your favorite grouch at Halloween parties, fan events, or casual movie nights. It’s funny, comfy, and unmistakably Oscar the Grouch.

Made from 100% polyester faux fur, this jumpsuit is basically a wearable blanket with attitude. A full front zipper makes it easy to pull on during a last-minute identity crisis, while elastic cuffs at the wrists and ankles keep the fur in place without cramping your comfort. The hood brings Oscar to life with embroidered eyes and a long-pile faux fur unibrow that radiates dont-mess energy. A printed Scram sign hangs from the shoulders, letting your mood and message do the talking while you quietly mutter insults to a nearby trash can. It’s officially licensed, so you can grouch with Muppet-approved flair.

Designed for plus-size, unisex wear, this Oscar the Grouch costume offers a roomy, comfortable fit that’s perfect for trick-or-treat routes, stage cosplay, or lounging on the couch in true grouch style. The versatile design makes it ideal for Halloween, theme parties, or any day you want to embrace your inner grouch.

Grouch Goals Activated: zip up, settle in, and celebrate the joy of being a little rough around the edges. When you’re fuzzy, green, and ready to judge, you’re not just wearing a costume—you’re stepping into character.
