Sneak out of the Upside Down in a Girls Demogorgon Onesie

The lights flicker, the walkie crackles, and something is coming through the wall. This Demogorgon onesie for kids brings the creature from Hawkins to the bedroom in dark grey flannel covered in black vines, the same tangled pattern that creeps across the Upside Down. The hood opens like the monster’s famous petal head, deep red with rows of cream teeth, and the Stranger Things badge sits on the chest. Ribbed cuffs seal the wrists and ankles, because even monsters hate a cold draught at night.

Boys Demogorgon Onesie for the bravest kid in Hawkins

Every fan of Eleven, Dustin and the Party has wondered what the other side feels like. These kids Demogorgon pyjamas answer with pure softness. The flannel is thick enough for October nights, the front zip opens in a flash, and two side pockets hold a torch for the walk down the hallway. Turn around and the word DEMOGORGON arches across the back over a red petal emblem. Halloween, binge nights or a friends-only sleepover, the monster is ready. Add it to the basket before the gate closes.

More creatures from the other side

For a parent and child duo, the Demogorgon onesie brings this outfit in adult sizes. The kids skeleton onesie shares the same spirit and makes a fun costume for a sleepover duo. More spooky designs are waiting in the Halloween onesies collection.

Frequently Asked Questions

They’re made to keep you warm on the sofa through autumn and winter, so yes, they’re cosy. The relaxed fit lets air move around, though, so you won’t get that stuffy feeling you get from tight pyjamas.
Machine wash at 30°C on a gentle cycle. Turn them inside out and pop them in a mesh laundry bag to protect the hood. Skip the tumble dryer and the iron. They air-dry quickly and fluff right back up on their own.
Yes, every onesie we sell is unisex. The roomy cut works for men and women alike, our kids’ styles fit girls and boys just the same, and our baby sizes are cut the same way for everyone. Just check the size chart to find your fit.
