Women’s Gir Onesie for the worst dog disguise in the galaxy

A tiny robot from planet Irk once zipped himself into a green dog suit and fooled absolutely nobody, and Invader Zim fans have loved him ever since. This Gir onesie for adults recreates the disguise in bright green fleece, with black sleeves and black legs from the knee down, a black zip up the front and a little black tail at the back. The hood carries Gir’s giant round eyes, a pink tongue flopping out, and two floppy black ears. Every stitch says doom, but softly.

Tacos, waffles and a Men’s Gir Onesie for the sofa

Gir never followed a single order, and the adult Gir onesie does not ask anyone to either. The roomy cut is built for sprawling in front of cartoons, elastic cuffs hold the black sleeves in place, and the zip opens fast when the snacks arrive. It works as a Halloween costume, a convention outfit that Nickelodeon kids will recognise instantly, or the most comfortable pyjamas a robot could dream of. Add it to the basket and sing the doom song all the way to the checkout.

More visitors from outer space

The alien onesie shares the same playful spirit and works well for group outfits. Finally, the adult onesies collection covers every other design for grown-ups.

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.
