Description
You step in, pull the hood over your head and smile. Two little fangs show up at the corners of a mouth that takes over the whole hood, and suddenly everyone wants a picture. That's the Fang Onesie: pointed ears, a big grin and a soft fleece body you'll want to live in.
Cream looks sweet until it smiles. Charcoal adds two little bat wings at the sides and doesn't pretend at all. Pick yours, or get both and let the photo decide who's the nice one.
It's a pajama first: soft, fuzzy fleece, an oversized fit you can curl up in, and adult sizes M to XXL chosen by height. Wear it to the Halloween party, then keep it on for movie night and every cold evening after.
Additional Information
Shipping & Returns
Packed and handed to the carrier within 24 to 48 hours, with tracking.
Delivery typically takes 8 to 15 days once shipped (around 9 to 17 days door to door). Our plush toys ship from our partner fulfillment centers, which is why it takes longer than a typical US-only retailer.
Changed your mind? Returns accepted within 30 days, unused.
Payment & Guarantee
Secure payment by card, PayPal, or Apple Pay. Your payment details are encrypted and never pass through our store.

Everyone else shows up in a costume. You show up in something you could fall asleep in, with two fangs grinning out of the hood. Guess who ends up in the middle of the picture.
Stand next to someone in Cream, put on your best spooky face and wait for the laughs. It takes two seconds to put on, and nobody forgets it.
Once the party's over, the Fang Onesie turns back into what it really is: a roomy fleece pajama. Soft on your skin, long in the arms, loose enough to pull your knees up on the couch.
Put on a scary movie, grab the blanket you won't need and settle in. You'll forget you're wearing a monster until someone walks in.


Cream and Charcoal were made to stand side by side. Match with your partner, your best friend or your roommate, and the photo writes its own caption.
Sizes go by height, so you pick for the person, not the letter. Between two? Size up, it's meant to swallow you.
Go by height, not by the letter: M fits 5'1" to 5'5", XXL fits up to 5'11". The full chart is in the Additional Information tab. Sizes run small and the fit is meant to be roomy, so if you're between two sizes, take the bigger one.
Both. Wear it to the party, then keep sleeping in it. No makeup, no cape, nothing to assemble.
The fangs and pointed ears say vampire, the Charcoal wings say bat. Call it whatever you like, it works as all of them.
No, the Fang Onesie is adults only. For the kids, the Big Mouth Monster Onesie comes in kids sizes, so the whole family can still match.
The onesie in your color and size, plus a pair of fuzzy slippers.
Turn it inside out, machine wash cold on a gentle cycle, then tumble dry low or hang it up. No bleach, no iron. Wash it with soft things so the fleece stays fluffy.
It's the gift that gets tried on the second it's unwrapped, and photographed two minutes later. Order early for the holidays and check the shipping times in the Shipping & Returns tab.
