Why we love onesies

Honestly, wearing onesies feel like you’re wrapped in a soft blanket. The thing is, onesies won’t run away from you in the middle of a cold night. Remember those sheets falling off the bed right when you need them most? Besides, admit it, the lace and thin satin cloth of your 'normal' pyjamas can be a bit uncomfortable at night. Who cares about looking hot when you can’t sleep in peace?

The world has gone mad on for the all-in-one. The craze has been snowballing over the past ten years and its’ popularity isn’t slowing down. Well-known celebrities are often caught out in them and even post snaps of them on their social profiles! Remember when Ryan Gosling sported his onesie on the Ellen DeGeneres show? Well, that's why we love onesies.

Things to remember when purchasing your onesies

It's important that when buying onesies, like with any clothing item you choose, that you shop around, do you research and make a great choice. That's why we've compiled a few key areas to note below:

1. What are onesies?

Onesies are one-piece garments also known as bodysuits or all-in-ones. They are specifically designed to be incredibly comfortable to wear for lounging at home and bedtime. However unlike normal pyjamas, onesies have developed over time and are now readily-available in styles that allow you to wear them in any scenario - out with friends, at the park or in the garden. They allow unrestricted movement, they're cosy and often come in really funny designs.

2. Who are onesies for?

Anyone from anywhere can wear onesies; from newborns to kids, to teens and adults alike. These are for all ages! That’s the beautiful thing about them, they're is not gender or age specific and anyone can lounge about in comfort.

3. How can I find the right size for me?

To be able to find the perfect onesie for you or your friends and family, you must consider the height, chest and waist. While onesies generally come in a one-size-fits-all style, it still makes sense read our size guide where you will find size charts for babies, juniors, men and women..

4. What’s the difference between onesies and them good ole pyjamas

The most obvious difference is that pyjamas are usually a two-piece garment (top and bottom), verses onesies which come as an all-in-one. Other key differences are that onesies often come with extra features such as hoods, zips, closed feet and are generally much thicker in weight - all aiding the overall warmth and comfort.

5. How and when is it okay to wear a onesie?

Onesies are perfect for sleeping, nights-in on the sofa and costume parties. Many people have also begun replacing their tracksuits with onesies, be that for a run in the park or a session at the gym. While everyone has their own time, style and opinion on what and when to wear them, generally speaking they are dominantly used in the winter months. Let's be honest though, it's probably best to throw on your best clothes if going to a restaurant...

6. What is best style of onesie?

  • Urban plain and simple
  • Animals of all kinds
  • And, superheroes and other gimicks offer widest selection of designs and onesie types available on the internet. Whether you need the zipped-up, knee-length, or hooded onesies; ultimately the choice is yours. We suggest just getting stuck in and having a ponder.

The history of onesies

Pyjamas themselves date back to the 17th century when Great Britain introduced bedtime lounge-wear to its population. The next key marker was during the American Civil War in the mid-1900s whereby soldiers and cowboys wore a one-piece undergarment as an extra layer of warmth and protection, known as the Union Suit. While these were never brought into the mainstream population, it's worth noting that they were around at this time. This followed trend and was later used in the UK during World War II as a means to solve the issue of both warmth and fast-movement during air raids.

Fun fact: Winston Churchill is commonly known as the inventor and father of onesies. This is because it was he himself who designed the garment specifically for speed, allowing him to be ready and warm as fast as possible.

During the 1970’s a children’s book written by Geoffrey Hoyle entitled “2010: Living In The Future” predicted that everyone would be wearing jumpsuit-style garments in the future. Funny that by 2010, everyone has been caught rocking the most coveted one-piece clothing around... onesies. Not to mention the many other style of jumpsuits available. Today it is commonly accepted that Onepiece, a well-respected onesie manufacturer, brought the modern day version to popularity - dating back only to 2007, originating in Oslo, Norway.
