Women’s Great White Shark Onesie with fins wide enough to fill a doorway

This is the fancy dress version rather than the pyjama version. The great white shark onesie for adults keeps the grey back and white belly of the real animal, then adds wide side fins that stretch from the ribs and a long tail that drags behind you. The jaw hangs open above your face, red inside, with pointed teeth all around.

The flannel is dense enough to hold those fins upright instead of letting them flop, which is what separates this model from a flat printed outfit. A zip runs the full length of the front, the sleeves stay roomy and the whole piece still works as sleepwear once the party ends.

A film night gets its monster with the Men’s Great White Shark Onesie

An adult great white shark onesie is built to be seen. It takes up space, it casts a proper shark shadow on the wall and it survives an entire evening of people asking to try on the hood, which happens more often than you would think.

It also solves Halloween in one purchase, with no assembly, no face paint and nothing to fix at the last minute. Order it for a fancy dress party, a themed birthday or the pure pleasure of walking through the kitchen with a tail.

Sharks of every shape

The grey shark onesie keeps the same realistic grey in a simpler shape without the wide fins. For the classic look, the blue shark onesie remains the most recognisable of the range. Meet the rest in the shark 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.
