Waddle around in style with a penguin onesie

If you fancy getting kitted up in a funny penguin costume, then discover penguin onesies. Great for lounging around the house or heading out for a fancy dress party, enjoy some fun with a snuggly onesie.

A onesie is a one-piece costume that is designed to look like an animal or character. You'll find cute little details such as a face and a penguin beak on the hood, so prepare to wear your hood up for an ultimately cute, and comfortable, look.


Great for everyone, young to old, you can find an animal onesie in a unisex size for adults or kids. Browse Kigurumi onesies for soft and fleecy penguin sets that come in a size range that will fit anyone. You could even get a larger size for kids so they won't grow out of them, with the oversized fit meaning extra comfort.

Adult Onesies

Onesies are definitely not just for kids, you'll find a big range of onesies for adults that are great for wearing around the home. Although you can find penguin onesies for both men and women, most adult onesies tend to be unisex, based on just a height measurement, which means it's even easier to find your perfect penguin onesie. You can also share yours with a partner or sibling if they're lucky enough. Choose yours with buttons or a zip fastening, depending on choice.

Where to Wear

The best place to wear your onesie is snuggled up at home. They are made from soft and fluffy material so are great for throwing on over your PJs or just wearing alone to ensure you'll be warm and cosy all night long.

We know that penguins aren't afraid of going out in the cold, so if you're heading out to a fancy dress party, your penguin onesie will not only make a great costume but will keep you nice and warm all evening.
