What to Consider When Buying Baby Onesies
Babies grow out of their clothes every month, have skin sensitivities and prefer comfort over fashion. So, while it may be fun to shop for baby clothes, it can be quite a challenge. We considered the following factors when building our list of the best onesies of 2021.
Fabrics
Babies have sensitive skin, which is why it’s so important to pay attention to fabrics when buying them clothes. When shopping for onesies, make sure that they are made with breathable, comfortable, and non-irritating fabrics — like cotton, fleece, and bamboo rayon. You’ll also want to select a fabric that won’t shrink or distort itself the more you wash it because, let’s face it, your baby’s onesies will be put through the wringer. You can find more baby-friendly fabrics in this informative article.
Size
Your baby will double in weight a handful of times throughout their first year of life, quickly outgrowing their onesies in the process. You’ll need to pay extra attention to the size guide when making your order. But a good rule of thumb is to order a size up to account for random growth spurts.
You may also realize that some baby clothing brands offer true-to-size options, while others run too small or too large. At the bottom of this article, you’ll find a Baby Clothing Fit Chart that compares the fit of the most popular baby clothing brands.
Seasons
Another thing to consider is seasons, seeing as the colder months beckon for long-sleeved and full-leg onesies, while the warmer months call for short-sleeves and bare legs. This also relates to fabrics, and which ones offer more warmth vs. which ones offer coolness and breathability. If you’re ordering onesies in advance, be sure to consider the climate in which you live as well as the incoming seasons.
Quantity
The number of onesies you will need to buy will depend on how often you do laundry and how frequently your baby dirties their clothing. Generally, it’s safe to assume that your baby will go through one onesie a day and one pajama onesie every night. seven onesies and seven pajama onesies are about what you need your laundry every week.
However, if your laundry follows a bi-weekly schedule, a total of fourteen daytime and nighttime onesies may be warranted. The quicker you wash your baby’s clothes, the fewer onesies you will need. You may also want to have a few extras to keep in your baby’s diaper bag for an extra change of clothes in a pinch.
Functionality
One of the most important factors to consider when buying baby onesies is functionality. When your baby has a full diaper, you want to get them changed as quickly as possible — and that’s where onesies come in.
Most bodysuits close with snaps and zippers, making for a quick and easy diaper change. Some onesies even have crotch snaps, allowing you to change your baby’s diaper without removing the entire garment. You’ll want to stay away from onesies that have buttons since they take longer to put on and take off.
Design
The best part of buying baby onesies is getting to select cute and fun designs for your baby to wear. On our list, you’ll find everything from basic onesies and animal-themed onesies to funny bodysuits and customizable designs.
If you’re looking for a customizable onesie that you can surprise your friend, family member, or partner with, you can skip forward to the BlueSkyCreations Custom Baby Onesie — it’s the only customizable option on our list.
Type
With so many different types of onesies, it can be a little challenging to pinpoint which one is right for your baby. There are tank top onesies, sleeveless onesies, long-sleeve onesies, footed onesies, and much, much more. We’ll let you know what type of onesie we’re reviewing as we go through our list. But, if you’d like to know more about the different types of onesies and what they’re good for, we invite you to read our full guide.
Now that we’ve covered what to look for when shopping for baby onesies, let’s delve right into our top picks of the year.
Top 10 Best Baby Onesies 2023
1. Best Overall Onesie: Touched by Nature Organic Cotton Bodysuits
Editor’s Rating:
Quick Facts
- Fit: Sizes run large
- Type: Short-sleeved onesies
- Quantity: 5
Touched by Nature Bodysuits are made with 100% organic cotton. They’re super soft and comfortable, making them ideal for babies with skin sensitivities. There are tons of fun designs to choose from whether you’re looking to dress a baby girl or a baby boy. They offer unisex designs, too, which comes in handy if you are waiting until birth to find out your baby’s gender.
Touched by Nature Bodysuits have convenient crotch snaps, making it easy to change your baby’s diaper without having to remove the entire onesie. However, keep in mind that these snaps are the only ones present, meaning that you have to slip the bodysuit over your baby’s head to put it on. This isn’t usually a problem since Touched by Nature Bodysuits have stretchy necklines, but it can be a challenge if you have a particularly fussy baby.
What sets Touched by Nature Bodysuits apart from the other onesies on our list is their quality. These onesies are made with high-quality fabrics and exclude the use of fertilizers and pesticides. They won’t lose their shape in the washing machine and are very durable. Touched by Nature’s sizes do run quite large though, so make sure to size down.
If you’re looking for a soft and comfortable onesie that has snap enclosures along the torso and the crotch, check out the Blueleyu Side-Snap Onesies instead.
Pros
- Made with 100% organic cotton
- Crotch snaps for easy diaper changes
- Soft and comfortable
- High-quality and affordable value pack
Cons
- Sizes are much larger than usual
Editor’s Rating:
Quick Facts
- Fit: Sizes run small
- Type: Long-sleeve footed onesies
- Quantity: 3
Carter’s Simple Joys Footed Pajamas come in fun patterns for girls and boys and are some of the best fleece pajamas on the internet. They’re soft and cozy and will keep your little one warm throughout the cold winter months. They have zipper closures that go from the chin down to the ankle, making it easy to slip your baby in and out of their pajamas.
Carter’s Footed Pajamas are safe, too. The zipper has a snap-over tab that prevents your toddler from playing with the zipper head and sliding out of their pajamas. The booties also have some grip to them, so your toddler won’t slip and slide when walking on wooden floors.
When it comes to sizing, we recommend sizing up by at least one size. Doing so will prevent the pajamas from being too snug while adding a bit of length to the booties, which can be a little tight.
Carter’s Footed Pajamas are for babies aged 12 months and up since they’re made of fleece. If you’re looking for footed pajamas for children under the age of 1, Carter has a cotton alternative designed for newborns and infants.
Pros
- Zipper closure with snap-over tab
- Gripper-foot pajamas
- Super soft fleece/polyester blend
Cons
- Booties can be a little tight
3. Best Budget Onesies: Gerber Baby Solid Onesies
Editor’s Rating:
Quick Facts
- Fit: Sizes run small
- Type: Short-sleeve onesies
- Quantity: 5
Gerber Baby Solid Onesies are simple, durable, and affordable. They’re thin enough to be used as undershirts but thick enough not to be sheer. These onesies are made with 100% cotton and are super soft and comfortable. They have a pull-on closure as well as a stretchy neckline, making it easy to slip them on and off.
Gerber Baby Solid Onesies have crotch snaps for easy diaper changes. However, their snaps are known for being small, which can make them a little tricky to close at first, especially if you have large hands. Speaking of small, we recommend sizing up when buying Gerber Baby Onesies, seeing as their sizes run small, too.
If you’re looking for simple onesies that are free of brandings and logos, Gerber Baby Solid Onesies are a great choice. Their solid colors also make them compatible with DIY heat transfer stickers. However, if you’re looking for Gerber Baby Onesies that come in cute and fun patterns, check out the Gerber Onesies Multipack instead.
Pros
- Made with soft 100% cotton
- Stretchy neckline for easy pull-on closure
- Crotch snaps for easy diaper changes
Cons
- Fabric is quite thin
- Snaps are very small
4. Best Kimono Onesies: Blueleyu Side-Snap Onesies
Editor’s Rating:
Quick Facts
- Fit: Sizes run small
- Type: Kimono Onesies
- Quantity: 4
Blueleyu Side-Snap Onesies are so easy to put on and off. They’ll have you wondering how you ever managed to use pull-on bodysuits on your baby. They’re truly perfect for fussy babies. They have crotch snaps for easy diaper changes, too.
Made with 100% combed cotton, you can expect Blueleyu Side-Snap Onesies to be thick and buttery soft. We love how these onesies won’t lose their shape over time and how they don’t shrink in the wash. Depending on your needs, you can order Blueleyu Side-Snap Onesies in a short-sleeved style or a long-sleeved style.
Unlike the other onesies on our list, which have a round neck, Blueleyu Onesies come in a v-neck. The v-neck is a little deep, though, which may or may not be to your liking. The sizes do run small, and the torso is short, to begin with. So, it may be best to order two sizes up.
Due to their supreme quality and feel, Blueleyu Onesies are a little more expensive than traditional onesies. If you’re looking to get the best bang for your buck, you can get twice the amount of onesies for the same price when you side with the Gerber Baby Onesie Multipack. However, Gerber Baby Onesies do not have side-snaps.
Pros
- 100% combed cotton and very soft
- Side snaps and crotch snaps for easy changing
- It keeps its shape and doesn’t shrink in the wash
Cons
- V-neck is a little low
- Torso is a little short
5. Best Summer Onesies for Girls: Blueleyu Tank Top Onesies
Editor’s Rating:
Quick Facts
- Fit: True to size
- Type: Tank Top Onesies
- Quantity: 4
If you’re looking for an undershirt that can be worn under a tank top dress, look no further than the Blueleyu Onesies. These spaghetti strap onesies come in very cute and feminine designs. They have a little bow on the neckline, making them easy to pair up with fancier skirts, shorts, and pants.
Blueleyu Onesies are made of 100% cotton and are perfect for babies of all ages. They’re breathable and soft, but when it comes to stretch, they aren’t too giving. This isn’t too troublesome, however, seeing as it’s easy to slip your baby’s head through the neck hole of a tank top.
Blueleyu Onesies are known for running a little large but not enough to order a size up. Although they might be a little loose at first, this allows your baby to grow into them. To prevent these onesies from shrinking, be sure to follow the washing instructions to the T.
If you’re searching for a similar product for little boys to wear in the summer, take a peek at the Yoga Sprout Bodysuits. These muscle shirt onesies are adorable and comfortable.
Pros
- 100% cotton
- Very breathable and soft

6. Best Long-Sleeve Unisex Onesie: Hudson Baby Bodysuits
Editor’s Rating:
Quick Facts
- Fit: Sizes run small
- Type: Long-sleeve onesies
- Quantity: 5
Long-sleeve and medium-thick onesies, like the Hudson Baby Bodysuits, are a fantastic choice for babies born during the colder months of the year. They’re made of 100% cotton and are super soft — perfect for little ones with skin sensitivities.
Unlike Gerber Baby Onesies, which are long and narrow, Hudson Baby Bodysuits have a short and wide fit. This can be a pro or a con depending on your little one’s body type. However, keep in mind that Hudson Baby Bodysuits are prone to shrinking a lot in the wash.
This can be a problem since the sizes run small to begin with, which is why we recommend sizing up by one or two sizes. But even then, it’s best to hang these onesies up to dry to prevent shrinkage of any kind.
Hudson Baby Bodysuits have crotch snaps for easy diaper changes, and the fabric itself is quite stretchy, allowing you to pull the neckline over your baby’s head with ease. However, pull on closures can be a little tricky with fussy babies or babies with larger heads. So, if you’re looking for long-sleeved onesies that have snap enclosures along the torso, check out the Blueleyu Side-Snap Onesies instead.
Pros
- Made with 100% cotton
- Crotch snaps for easy diaper changes
- Soft and stretchy fabric
Cons
- Short and wide fit
- Prone to shrinking in the wash
7. Best Summer Onesies for Boys: Yoga Sprout Bodysuits
Editor’s Rating:
Quick Facts
- Fit: Sizes run large
- Type: Sleeveless onesies
- Quantity: 5
Yoga Sprout Bodysuits are known for their supreme quality and affordable prices. This little value pack consists of 5 sleeveless onesies that have crotch snaps for easy diaper changes.
They’re made of 100% cotton so they don’t have too much stretch to them. Still, pulling it over your little one’s head is made easy thanks to the large neck hole. While the sizes do run quite large, we don’t recommend sizing down because these onesies are prone to shrinking in the wash.
Yoga Sprout Bodysuits come in a few different designs, but the sleeveless option is just fantastic for the summer months. However, keep in mind that the fabric itself is a little thick, which is why using these onesies as undershirts is a safer bet in the colder months.
If you’re looking for 100% cotton onesies that can be used as undershirts, the Gerber Baby Solid Onesies are a great choice. However, keep in mind that these onesies have short sleeves and come in one solid color.
Pros
- 100% cotton
- Crotch snaps for easy diaper changes
- Soft and comfortable
Cons
- Prone to shrinking in the wash
- Material is a little thick for an undershirt
8. Stretchiest Option: Hanes Flexy Bodysuits
Editor’s Rating:
Quick Facts
- Fit: Sizes run small
- Type: Short-sleeve onesies
- Quantity: 5
Hanes Flexy Bodysuits are known for their ability to stretch in all the right places, allowing your little one to wear them for a lot longer than usual. Their 4-way stretch moves with your baby, allowing them to move around unrestricted. They also have expandable shoulders making it easy to fit the neckline over your baby’s head.
Hanes Flexy Bodysuits come in plenty of fun patterns. Some of these patterns are unisex, too, making them compatible with parents who want to wait until birth to find out their baby’s gender. You’ll also notice that they have big snaps — perfect for those of you with larger hands.
Hanes Flexy Bodysuits aren’t prone to shrinking in the wash. However, their sizes do run small, so it’s best to order a few sizes up. Unlike the other onesies on our list, the Hanes Flexy Bodysuits have a seam on the back that separates the bottom from the back. However, this seam can be uncomfortable once your baby begins to outgrow the bodysuit.
These short-sleeved onesies are made of 60% cotton, 37% polyester, and 3% spandex. So, while they’re stretchy, they’re not very absorbent. For this reason, we would recommend Hanes Flexy Bodysuits for toddlers and not newborns, who will be much more comfortable in 100% cotton — especially if they have skin sensitivities. Should that be the case, we recommend siding with Touched by Nature Organic Cotton Bodysuits instead.
Pros
- 4-way stretch with expandable shoulders
- Soft and lightweight fabric
- Large crotch snaps for easy diaper changes
Cons
- Only 60% cotton and not very absorbent
- They have a seam that separates the bottom and back
9. Best Multipack: Gerber Baby Onesie Multipack
Editor’s Rating:
Quick Facts
- Fit: Sizes run small
- Type: Short-sleeved onesies
- Quantity: 8
The Gerber Baby Multipack offers eight adorable onesies for a very reasonable price. They’re 100% cotton — a breathable and non-irritating fabric that is perfect for children of all ages.
These short-sleeved onesies are a little different than the other ones on our list because of their snap enclosures, which are a lot higher up than usual. This allows you to see the snaps while fastening them, which is perfect for anyone with larger hands.
Gerber Baby Onesies are prone to shrinking in the wash, so be sure to wash them on a cold cycle and hang them up to dry to keep them as is. The sizes are a little on the small side, too, so be sure to size up.
Gerber Baby Onesies don’t have a lot of stretch to them. They aren’t all that soft either, but that’s nothing a little baby-safe fabric softener can’t fix. The fabric is on the thin side, too, making them better suited for summer than winter. They make for great undershirts due to their lightweight breathability.
If you’re looking for cotton onesies of the thicker and softer variety, we recommend looking into the Hudson Baby Bodysuits instead.
Pros
- 100% cotton
- Have a higher crotch snap than usual
- Very affordable and cute multipack
Cons

- Shrinks in the wash
- Fabric is a little thin

Guide to Buying the Best Baby Onesies
Besides comfort, functionality, and quality, there are a few other things to consider before filling up your baby’s wardrobe with onesies. In this complete buyer’s guide, we’ll go through the benefits of baby onesies while also delving into the many different types of onesies, what they’re used for, and how to wash them. You’ll also find a FAQs section at the end of this article, so read until the very end to get some answers.
Benefits of Baby Onesies
Any parent will tell you that baby onesies are a lifesaver. They’re easy to slip on and off, have crotch snaps for easy diaper changes, and you can buy a large volume of them for a very reasonable price. Their low price point is a perk considering that babies go through outfits as quickly as they do diapers.
Baby onesies can also be used as undershirts, keeping your baby warm no matter the season. Most importantly, however, their snaps keep the onesie in place. This prevents your little one from pulling their shirt over their head, which can be especially dangerous for a newborn. It also stops toddlers from taking off their clothes, which is a bonus considering how much they love to parade around in their birthday suits.
Different Types of Baby Onesies
There are tons of baby onesie styles to choose from, but it all boils down to which type works best for your child. You’ll find the following types of baby onesies on our list.
Tank Top Onesies
Tank top onesies are perfect for the summertime. They’re light and delicate and often worn by little girls. They make for great undershirts in the colder months, too. If you’re searching for a cotton tank top onesies, we highly recommend the Blueleyu Tank Top Onesies.
Sleeveless Onesies
Sleeveless onesies are also a great option for the summertime. They’re light and breathable and truly a staple piece for the warmer months. The Yoga Sprout Bodysuits are the only sleeveless onesies on our list. They’re perfect for little boys and have some very cute designs on them.
Short-Sleeve Onesies
Short-sleeve onesies are the most common type of onesies. You’ll go through tons of these whether you’re raising a newborn, an infant, or a toddler. You can use them as is or use them as undershirts.
There are a few short-sleeve onesies to choose from on our list, but our favorites are the Touched by Nature Organic Cotton Bodysuits and the Gerber Baby Solid Onesies.
Kimono Onesies
Kimono onesies, otherwise known as side-snap bodysuits, are practical beyond belief. They’re the only type of onesie that has snap alongside the torso. This makes it a lot easier to dress your baby, especially if they’re fussy. This is because you don’t have to slip the onesies over your baby’s head like you would a t-shirt.
Instead, you can snap open the kimono, lay your little one on top of it, and snap it closed. Kimono onesies also have crotch snaps so you can change your baby’s diaper without removing the entire bodysuit. Check out these videos to see the difference between putting on traditional onesies vs. kimono onesies.
Kimono onesies also have crotch snaps so you can change your baby’s diaper without removing the entire bodysuit. If you’re interested in trying out a pack of kimono onesies, check out the Blueleyu Side-Snap Onesies. In this entry, you’ll find links to both short-sleeve and long-sleeve options.
Long-Sleeve Onesies
Long-sleeve onesies have long sleeves that keep your baby warm during the colder months of the year or during nap time. If you’re looking for a pack of long-sleeve onesies, check out our entry on Hudson Baby Bodysuits, where you’ll find adorable designs for both girls and boys.
Footed Onesies
Footed onesies usually come in a long-sleeve format. They’re often used as sleepwear and for early morning and late-night playtime sessions. Some booties even have grips on the soles to prevent your little one from slipping and sliding.
The 3-pack of Carter’s Simple Joys Footed Pajamas is our top pick. These onesies are super soft and comfortable. They come in cute designs for both girls and boys and are the only onesies on our list that have a convenient zipper closure.
What You Need to Know About Washing Baby Clothes
Washing baby clothes isn’t as easy as washing adult clothes. First of all, you need to consider the kind of detergent you use and ensure that you’ve selected one that is safe for babies. Babies have skin sensitivities and are not yet used to the harsh environments we live in. For this reason, you must wash your baby’s clothes before placing them on their body.
You’ll also want to pay close attention to washing and drying cycles since baby clothes are prone to shrinking. Baby clothes are often made of 100% cotton, and so it may be best to hang your onesies up to dry to keep their shape and size intact. However, it is usually safe to dry onesies on a low heat setting but check the tags to be sure. Now and then, you may also be required to hand wash delicate baby items.
Frequently Asked Questions (FAQs)
Which Brand Is the Best for Baby Clothes?
Burt’s Bees has often been referred to as the best baby clothes brand. We especially love their unisex onesies, which are made of 100% organic cotton and known for their softness. However, we must admit that their branding can be an eyesore, which is why we didn’t include Burt’s Bees Onesies on our initial list.
If you’re looking for soft and comfortable onesies that are made of 100% cotton but don’t want your baby sporting large logos on their chest, we highly recommend siding with Touched by Nature’s Organic Cotton Bodysuits. If Touched by Nature isn’t your preferred brand, you can also side with Carter or Gerber, both of which are reliable and reputable baby clothing brands.
Are Onesies Good for Babies?
Yes. Rompers, onesies, and bodysuits are very comfortable. They’re known for being a newborn’s go-to clothing item because they wrap around their diaper and don’t ride up their back or belly as they move. Onesies are good for babies as long as they aren’t too tight on them.
What Size Do Babies Wear the Longest?
Every baby is different and grows at their own pace. The size they wear depends on how quickly they grow, which may cause some to grow out of their clothes faster than others.
During the first year of your baby’s life, they will double in size a few times over. Their growth spurts will come to a slow at around 12 months. With this in mind, babies usually wear this size the longest.
Last Thoughts
The first few years of your baby’s life will be jam-packed with late nights, heaps of laundry, and incredibly sweet moments. And before you know it, your baby will grow out of their baby clothes and become a little person of their own. Luckily, you’ll still have their tiny onesies to remind you of how much they have grown.
We hope that our guide has helped you find the best baby onesies for your family and wish you and your little nugget all the joy in the world.
