Great White Shark Onesie

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

This is the costume version rather than the pajama 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 costume. 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 costume 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 recognizable of the range. Meet the rest in the shark onesies collection.
