What are Baby Onesies?

Baby onesies are just what their name states-a one piece outfit for your baby. They are short sleeved or long sleeved and they have snap at their bottom around the crotch. Onesies can be plain and white, colored, or printed. They come in all kinds of sizes, from newborn all the way up to 24 months! 

Onesies are basically undershirts. They form a layer and barrier for babies so that their clothes fit better, feel more comfortable, and that chafing doesn’t occur. Onesies keep your baby covered and also provide a layer of warmth. 

Onesies for baby are also pajamas. Designed with a covered foot, with long or short sleeves, these one piece outfits are virtually a sleep sack with arms and legs built in.

Versatile Clothing

Baby onesies are useful because they make your baby feel safe and secure. Once a baby is first born, many moms bring onesies into their hospital bags so they can put it on their baby so they have a barrier between the baby and its hospital swaddle, which it will often be in. 

Baby onesies are useful because they allow for quick and easy diaper changes. Simply unsnap the bottom and the baby is ready to be changed. Parents especially love this feature for when their little ones are napping or sleeping overnight and need changing. Parents don’t have to wake them up. They can unsnap, change them, and be on their way. 

Baby onesies help your baby sleep. They make for great lounge outfits, especially when you first come home from the hospital because you don't need to dress them in any special outfits since you’ll be home all day for at least the first week. 

Durable Materials 

Baby onesies are designed most often in 100% cotton. This fabric is thick, yet lightweight and breathable. It is comfortable and soft, so it won’t irritate your baby’s delicate skin. Cotton washes and wears well, is strong, and doesn’t typically rip or fray. Cotton also has a little bit of stretch to it. 

Some other onesie baby can be made from Muslin cotton, a different variation of cotton. It too is lightweight and breathable, and it gets softer with every wash. 

You can also find cute baby onesies designed in a cotton blend, which can be mixed with rayon or polyester, giving it ultimate stretch and making it a wonderful layering item. 

Some onesies are designed with a heavier fabric, such as fleece, wool, crushed velvet, or sherpa. This fabrics are awesome when used on pajamas, especially during cold, winter months!  Great to sleep in or lounge in, parents love that their baby can wear something ultra-soft and warm, and they still have the ease and convenience of a quick diaper change. 

As mentioned before, onesies can be organic, colored using natural dyes. They can be all kinds of colors, prints, and patterns. However, onesies are most popularly picked up in a plain, white color so they are versatile enough to wear with anything. 


A onesie is appropriate to be worn anywhere! In fact, a onesie is one of the first things your baby will wear. It is no fuss, effortless, and versatile. 

Moms put their baby in onesies during playtime, feeding time, and after a bath. Because they layer well, your baby can wear a onesie underneath a dress, sweater, long sleeved knit, or even with a skirt and t-shirt!

You can even purchase a onesie in the form of a pajama! These long sleeved and full footed pieces still have a snap bottom feature and can zip up in the front or back!

Baby onesies can be styled in many ways. If you want to create a casual outfit, you may consider picking up onesies that have a graphic print or saying on it, creating two shirts for one! You can slide on a pair of joggers or leggings and crib socks and shoes when out for a walk. Not only does this casual outfit work for both genders, but it helps you dress them quickly, with ease, and it keeps your baby comfortable. 

For more formal events, your baby can wear a onesie under a ballerina or princess style dress and your little guy can wear one under his miniature and adorable three piece suit. 


As you are putting a onesie on your baby, did you ever wonder where they came from? If you think about it, their design is genius! Onesies date all the way back to the time of Sir Winston Churchill! 

A wearer of “adult pajamas,” Churchill was often spotted in this one piece get up. Eventually, union workers started wearing siren suits, which were sleeveless and designed in a short style to put underneath their work uniforms.  Eventually, women got in on the action, and so did kids. 

While babies and toddlers most often wear these one piece layering pieces and pajamas, older kids and teens have been wearing onesies decorated like sharks, unicorns, and other creatures; around their home when lounging or watching tv!

Who knew that baby onesies have been around for ages! Their material, prints, and design helps parents to dress their little ones, line their outfits, and keep them cool and comfortable all year round. If you are putting together a onesie basket, be sure to get a wide range of sizes, colors, designs, and fabrics so the mom in your life will always have one on hand for her baby boy or girl!
