Cookies First, Questions Later
If your snack stash mysteriously disappears, this Adult Cookie Monster Zip Costume might be to blame. Cozy, fuzzy, and officially licensed, it’s everything you love about Sesame Street’s hungriest blue monster—minus the constant crumb mess. Whether you’re hitting a csotume party, lounging on the couch, or declaring your lifelong commitment to baked goods, this onesie makes sure you do it in peak monster style.
It’s simple, it’s snuggly, and it’s guaranteed to make you crave dessert. Just be prepared—once you put this on, friends may start guarding their cookie jars.
Product Details
This onesie is crafted from soft polyester fibers that give it that classic Cookie Monster fuzz, perfect for hugging, snacking, or both at the same time. A full-length zipper runs down the middle, making it easy to slip on or off between treat breaks. Rib-knit cuffs at the wrists and ankles keep the cozy fit secure while adding a touch of stretch for comfort.
The attached hood is the star of the show, featuring fiber-filled plush eyes stitched on top. Their slightly askew placement captures Cookie’s wide-eyed, cookie-obsessed personality perfectly. The design is lightweight enough for all-day wear, yet warm enough to keep you cozy during chilly nights. Pair it with a plate of chocolate chip cookies, and you’ve got a costume and a snack plan in one.
