Questions we get asked

Who is a monster onesie for?

For every grown-up kid: your other half, a brother or sister, the colleague you drew in Secret Santa, the friend who loves a pyjama party… From S to XXL it fits women and men alike — the present that gets a laugh when it's unwrapped and then gets worn all winter.

Which size should I choose?

Go by the wearer's height: S under 150 cm, M for 150–160 cm, L for 160–165 cm, XL for 165–170 cm, XXL for 170–180+ cm. Between two sizes? Take the larger one — the cut is deliberately roomy. Every style has its own size guide on its product page.

Is it a costume or real pyjamas?

Both! The horned, big-eyed hood steals the show at a party, but the thick fleece flannel makes it above all a proper loungewear piece — warm, comfortable and machine washable. A fun one-piece you keep wearing long after the party.

Sizing, care, delivery… every answer is in the product page FAQ.
