What is a Onesie?

By definition, a onesie is a one-piece leisure garment that is worn over the torso to the legs. There are variations of a onesie that are sleeved, hooded, and pantless, depending on what you’re looking for.

Rather than a daily wear choice as they would be for infants and toddlers, onesies for adults are primarily pajama options, with jumpsuits sometimes being for outdoor wear. Onesies are made from materials such as knit cotton, fleece, and chenille.

Are Onesies Just for Kids?

Absolutely not! Though you may not wear them as much as an adult, onesies are a trend that has no intention of dying out. Use them as sleepwear as well as fashion, or simply wear them for fun when you go out! Onesies are multifunctional one-piece suits that you can enjoy at home or on the go. They are made to be warm and comfortable, so don’t be surprised if your onesie instantly becomes your favorite piece.

Pros and Cons of Adult Onesies

— Comfort

This is the best point of onesies: they’re super comfortable! The material and the fitting make them the perfect outfit to wear at home or when you’re sleeping since your comfort comes before anything else.

— Personalization

One thing you’ll notice about onesies is that variety never seems to end. There is always going to be a design or style which is perfect for you, all it takes is a little looking around. Whether you want a festive or toned-down onesie, you’ll find exactly what you need in the mass market.

— Fun

There’s no doubt about it, onesies are a lot of fun. They’re simplistic, they can come in the silliest and craziest designs, and they make selecting your outfit much easier. It’s always fun to see people’s reactions when they see you in your favorite onesie at home, more comfortable than you’ve ever been before.

What is the Best Material for Onesies?

• Cotton

The most common option you’ll come across is cotton. Cotton is a natural fiber that’s lightweight and breathable. Its appeal comes from how inexpensive and comfortable cotton is, and how easy it is to maintain. Most onesies made from cotton are machine washable, so you don’t have to worry about the maintenance hassle.

Cotton is prone to shrinking, especially after the first wash. This means your onesie might feel tighter after throwing it into the washing machine.

• Polyester

Another common fabric to stumble across, polyester is cotton’s synthetic cousin. Like cotton, polyester is a lightweight and breathable fabric and tends to be the budget pick many people are looking for. It does not compromise on comfort, and it’s made from thermoplastic making it a stretchy fabric.

Polyester, unlike cotton, however, is not made for warmer weather. You’ll find polyester can get sticky and may be uncomfortable to wear in higher temperatures. It’s also not a sustainable fabric option, which can be extremely important to many people.

• Wool

Wool, as everyone knows, comes from the coat of different animals. Wool is warm and soft, as well as a natural fire retardant. It is wrinkle-resistant, moisture-wicking, and insulting, making wool the preferred material to consider for your winter clothes.

Wool, being a natural fiber, is prone to shirking much like cotton is. There is also a higher level of maintenance required to keep woolen clothing clean and wearable. Wool clothes will most probably have to be hand washed and air dried out of the sun to prevent further shrinking.

• Fleece

This is yet another well-known fabric that many people are familiar with. Fleece is a combination fabric, meaning there are other fabrics used to create this one. Common fleece variants are cotton fleece, wool fleece, and polyester fleece.

Fleece is a comfortable, warm, and breathable material that is used best for chillier weather. The material is water repellant making it a better option for daily wear and it’s hypoallergenic, so it’s excellent for those who are sensitive to allergen triggers and need friendlier materials.

Fleece is not the same level of quality as wool or cotton, so you can expect it to pill and wear sooner than most other fabrics. Fleece can also be harder to clean if they are not machine washable pieces and they can retain body odor quicker.

Keep in mind that it’s more of a winter material like flannel pyjamas, because of how warm it is. If you’re looking for something to keep you cool, then opt for some cooling pyjamas.

What to Look for in a Onesie for Women

There is a lot more to consider if you’re going to buy yourself the perfect onesie, and we have all of the considerations jotted down for your convenience.

— Sizing

The sizing for onesies is standard. There are men, women, and children sizes to choose from. It’s best to purchase a onesie that’s one size larger than your actual size since there is a chance of shrinkage if the material is wool, cotton, or fleece.

Some onesies are made from a more flexible fabric, while others a fitting and form-shaping. If you’re looking for the latter, then use reviews and accurate measurements to make the best decision possible. A onesie that is too small or tight can decrease your mobility and become quite uncomfortable.

— Material

The material depends on when you want to wear your onesie and how often you want to wear it.

If you plan on wearing it all year long, then material such as cotton or polyester is the right way to go. They’re breathable and stretchier fabrics that can allow for airflow in the summers, but they insulate and keep you warm in the winters.

If you live where winters are too frigid for materials such as cotton, then look into alternatives such as wool and fleece. These fabrics are much warmer and comfortable, perfect for chilly nights. They are, however, harder to maintain since they don’t always come machine washable. Be ready for some additional maintenance if you’re going to buy a winter-specific onesie.

— Cost

Onesies are cheaper alternatives in comparison to nightgowns and pajama sets. A onesie, being only one piece in a purchase, is an economically wise choice, since it’ll serve its purpose and save you extra costs.

The price range for a quality onesie should be around $30-$50”. Anything underneath this price should be assessed skeptically, and anything above this range should be looked at incredulously.

— Quality

There is no compromise on quality. The stitching, the material, the durability, all of this falls under the level of quality the onesie has to offer. The best way to know the quality is to check the reviews and comments other buyers have made. If they see a compromise in quality, then it’s best for you to take this into consideration before making your final choice.

— Design

This is where the fun begins. Onesie designs can be animals, superheroes, characters, and more! You can choose your onesie from a wide variety of patterns and colors to suit your personality best. There are even simplistic designs in case you’re not too big on the more extravagant designs, but truth be told you haven’t experienced the full glory of a onesie until you’ve run around in an animal costume.

— Convenience

There is a lot to consider when you look for convenience in your onesie. What accessories can you get that will optimize your comfortable experience?

First, there is the consideration of a footless vs a footed onesie. You can either cover yourself all the way down to your toes, or you can get footless ones and wear your own socks and shoes as you please.

There are also hooded onesies as well. There are no shortcomings to having a hoodie since it’s your choice whether or not you want to wear it. It’s great to have the option in case you need to make it through cold winters in your onesie.

Then there is the back flap. A back flap is there so you can easily go to the washroom without having to remove the onesie every single time you go. It’s extremely convenient but increasingly less popular. Some people are perfectly content with wearing a onesie that doesn’t have a back flap and removing the whole piece whenever they need to use the washroom.

Pockets are yet another consideration of convenience which you have to think about. Not all onesies come with pockets, and it’s very easy to miss out on them if you’re not paying attention. There are side and front pockets that typically come with a onesie.

Zippers and snaps are the final consideration based purely on preference. Whichever you find easier to use, stick with that one. The truth is if you’re investing in a quality onesie, these features should not be an issue.

Bottom Line

Onesies are fun and extremely comfortable pieces of clothing to own, and there is no age restriction on who can enjoy them. Buy yourself a onesie to find out what true comfort feels like and be sure to share this article with any other women who you think should do the same.
