It Looks Ridiculous and Feels Like a Blanket: 5 Reasons People Buy the Monster Onesie for Themselves
Plenty of people buy this onesie as a gift. Plenty of others buy it for themselves, or for a best friend, and then wear it far more than they planned to. It looks completely ridiculous. It is also warm, loose and soft enough to live in. Here are five reasons it has become the first thing some people change into when they get home.
It Wins the End-of-Day Outfit Change
There is a moment at the end of a long day when the real clothes come off. Most people reach for an old hoodie and whatever sweatpants are nearest. Some people reach for a plush monster suit with googly eyes and shaggy hair, and they do not regret it.
It is loose from the shoulders to the ankles, with long sleeves and a hood, in fluffy sugar fleece that is soft on the inside. It is the kind of outfit you forget you are wearing until someone walks in and starts laughing.
A verified buyer: “I love it, I wear it almost everyday day and it is extremely soft”
The Fit Is Oversized on Purpose
There is one roomy adult size: 63 inches around the chest and 54 inches long. It is meant to hang loose, the way a blanket does, rather than sit close like pajamas.
How it sits depends on your height. Shorter wearers get extra length that gathers at the ankle, and taller wearers get a higher hem. It zips from low on the leg, not up the front, so a fit check in the mirror shows the whole monster, face and all. The first time, zip slowly and hold the fleece back so it does not catch.
A verified buyer: “Other than it being a bit big I love it! I’m 5’2 for reference”
It Is Warm Enough to Leave the House In
It does not always stay indoors. It is warm fleece with long sleeves and full-length legs, which makes it a reasonable choice for a quick trip outside on a cold morning, as long as you are fine with a few double takes.
The hood is the warmest part. With it pulled all the way on, the monster face covers your eyes, which is excellent for the joke and less useful on a sidewalk.
A verified buyer: “Love love love!!! I wear it everyday 😂😂 definitely to the bus stop on cold mornings!”
It Is Better With a Best Friend
The funniest version of this onesie is two of them side by side. Best friends pick two different colors and film the fit check, the dance or the slow walk into a room together.
Two onesies are $79.99 together, and orders of $75 or more ship free. Each one comes with its own comb, so nobody has to share.
Cold Evenings Are What It Is For
As the weather turns, the onesie earns its place. It comes out for chilly evenings on the porch, movie marathons, sleepovers and the first properly cold night of the year.
Nobody needs a monster onesie. That is exactly what makes it fun to own one. Laugh first. Then live in it.
A verified buyer: “So cute and well made. Cant wait for camp fires this fall”
