Once upon a wardrobe door, the Women’s Boo Monsters Inc Onesie

Once upon a time in Monstropolis, a little girl slipped through a wardrobe door and turned a whole city of scarers upside down. Her laugh lit up the factory, her giggles followed Sully down every corridor, and she tiptoed past Randall wrapped in a purple monster disguise. This Boo Monsters Inc onesie for adults brings that disguise back in soft lilac fleece, with a hood crowned by a shaggy grey tuft, two round stalk eyes and a ring of white fangs around the face. The tale begins again the moment the zip closes.

Men’s Boo Monsters Inc Onesie for giggles louder than any scream

Every adult Boo Monsters Inc onesie keeps a spark of that fearless spirit. The fleece jumpsuit wraps the evening in warmth, the ribbed cuffs keep the sleeves of these pyjamas in place during film marathons, and the hood turns any doorway into a portal to the scare floor. Pair it with a Sully costume and the nickname Kitty will echo all night long. Halloween parties, couples’ costumes and lazy Sundays all feel lighter in this kigurumi. Add it to your basket, step through the wardrobe door and let the laughter keep the city running.

Friends from the scare floor

The Sully onesie brings her big blue best friend along for the adventure. More heroes from Pixar and every studio classic wait in the Disney onesies collection. Other cosy characters for grown-ups fill the adult onesies range.

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.
