How Do I Choose the Best Adult Onesie?

Today, we all agree that onesies aren’t just meant for babies. Adults have come to appreciate that these loungewear suits are not only comfortable but also easy. Love them or hate them, adult onesies are the pinnacle of fashion cool. A onesie, righteously rocked, will make you feel sexy and confident.

Just like a bathrobe, a onesie is a relaxing choice for those lazy days at home enjoying a movie on a stylish smart TV and chowing down on some crunchy popcorn.

Onesies make life easy. A onesie saves you the hassle of finding a matching top and bottom, or the time wasted in locating the missing half of your pajamas. This is a one-piece-only deal -- just slip it on and you’re set!

Onesies come with lots of comfort. Unlike nightgowns, well-fitting onesies don’t require regular adjusting. Even better, they’re designed to make you look cute. Onesies are super trendy, and with the right fit you’ll elicit that ‘stop and stare’ response in the streets.

However, with so many varieties to choose from, getting the right one can be a challenging task. Read through our guide and understand the factors to consider before adding a onesie to your wardrobe.
A good-quality onesie is priced between $10 and $50. The price depends on features such as material, brand name, and design, among others. For instance, you’ll pay more for models made of high quality cotton than for those made of polyester. Similarly, unisex designs are more expensive than onesies meant for one gender only.

Be cautious when you come across cheap adult onesies, as most of them are made of low quality materials that don’t last. You don’t want to use your hard-earned dollars on substandard items.
One of the main features to consider before purchasing a onesie is the material. Get a onesie that is made of high-quality material for longer life. If you need a warm onesie, check out the thickness and the type of fabric. Whatever fabric you decide on, make sure you’ll be comfortable in it.

Here are the important qualities to look for before purchasing an adult onesie:
  • Type (men’s, women’s, or unisex)
  • Material (cotton, polyester, fleece, etc.)
  • Fit and size
  • Design (hooded, open or closed feet, flap, or animal design)
  • Color options
  • Hand- or machine-washable
Now, let’s examine these factors in detail.
Construction and Design
Various brands offer different onesies targeting different groups. For example, onesies for men tend to be large and dark-colored, while women’s are smaller and brighter. Unisex onesies are mostly medium-sized and available in many colors. Choose the type and color that inspire and complement your lifestyle. Donning a onesie in your favorite color can make you feel elegant, confident, and comfortable.

Consider the material of the onesie before purchasing it. Common materials are cotton, polyester and fleece. If you’re looking for a onesie that will keep you warm, fleece or polyester will work for you. Fleece is ideal in cold weather, but might be uncomfortable for sleeping. Polyester might keep you warm, but probably won’t last long. On the other hand, cotton onesies are ideal during the summer.

Onesies come in different designs with divergent features. For example, do you want a footed or footless design? If you’re looking for extra warmth, a footed design will work for you. However, if you like to wear shoes or slippers, you would be better off with a footless version. Do you want a hooded or hoodless onesie? Having a hood really brings no drawbacks; you can choose to wear the hood or leave it depending on the weather conditions. If inconvenience in using the restroom bothers you, consider a onesie with a back flap.
Performance and Ease of Use
Consider how easy it will be to keep your onesie clean: is it hand- or machine-washable? Also, if you’re looking for an outdoor model and are concerned about the hems getting dirty and wet, a footless model will be ideal for you.

Be sure you’ve thought about the weather when you’ll be wearing your onesie. You don’t want material so thick it will make you sweaty in hot sun, or so thin you’ll shiver when the snow falls. Make sure you will be comfortable in your onesie, whenever and wherever you wear it.
