We’ve all seen those utterly adorable baby clothes and took a moment (or more!) to gush. There’s something about tiny human clothes, isn’t there?

When it’s time to buy, it may become a little more complicated. Baby’s clothes are called different things. There are certified standards to consider because of their delicate skin. Do you need long or short sleeves? You might even be surprised a baby’s temperature varies quite a bit, and so the sleeves very much matter!

We’ve put together a diverse list of the seven best baby onesies (an umbrella term for the many varieties) you can buy or gift in 2020. Don’t forget to read to the end for the FAQ if you’re still not sure which kinds to get.

Baby Onesies — cute and cozy!

1. Gerber Organic Short Sleeve Onesies Bodysuits

(Best value — $)

Gerber Organic Short Sleeve Onesies BodysuitsWhy it’s great: Any mom will tell you how quickly we go through onesies. We’re lucky if we do just one change in a day. Gerber sympathizes with us. You’ll need to add at least one pack of their white 100% organic cotton short-sleeved onesies to your cart. You’ll probably use it all in a week or less. All of their onesies are sized for preemies up to 12 months.

Does it get better? Yes! The neckline is expandable for quick changes. We all know how fast kids want to be changed. The ribbed leg opening makes it a comfortable fit for your little one, too. To complete the change, the snap button closures are higher for ultimate convenience.

Keep in mind: Sizes may run small, so try ordering a size up, especially as cotton does shrink in the wash. The material is thin but soft and works more for warmer weather or as an undershirt. These come in a pack of 5 or 15 short sleeves.

Best for: Parents seeking a value pack of white onesies.

4. Burt’s Bees Organic Romper-Jumpsuit

Burt's Bees Organic Romper-JumpsuitWhy it’s great: A sleep and play outfit is necessary for babies who are always on the go. This GOTS certified organic breathable cotton one-piece is designed optimally for newborns up to 9 months.

It fits loosely enough to allow wiggle room for any activity. You’ll find scratch-free convertible mittens on sizes newborn up to 3 months. The non-slip foot grip is perfect during playtime to reduce falling accidents. When it’s time for one of the many changes, undo the nickel-free snap tab to open the diagonal front zipper, which makes getting in and out just a little easier. The zipper guard assists in avoiding accidental pinching of your baby’s skin, too.

Keep in mind: Size runs a little large, but your little one will quickly grow into it. Some parents found the material to be a bit thin, so it’s best for warmer nights. Comes in a one pack.

5. L’ovedbaby Organic Kimono Bodysuit

(Best bodysuit style — $)

L'ovedbaby Organic Kimono BodysuitWhy it’s great: It’s a unisex bodysuit styled as a kimono. It doesn’t get more unique than this! Actually, it does. These outfits come in 12 beautifully rich colors, including seafoam, eggplant, and stone. Find this adorable style in sizes preemie/newborn (4-7lbs) to 6 months (22lbs). It goes on easy thanks to the wrap design and front snap closure. That means no over the head shenanigans. We all know how much babies don’t like anything going over their adorable faces.

Unlike other bodysuits, the L’ovedbaby brand is ethically made in India. This cotton blend is also GOTS-certified, which means it contains none of the usual chemicals found in clothing such as flame retardants and solvents. This is the kind of body-hugging suit you want against your baby’s delicate skin. You’ll also find gloved sleeves to keep your baby’s hands warm (except in sizes 6-9 months).

Keep in mind: While these are long-sleeved bodysuits, you’ll need to put your baby in pants if necessary. Most customers encourage ordering one size larger, but because of the style, they are supposed to fit somewhat loosely.

FAQ’s about best baby onesies

1. Should I get onesies, bodysuits, jumpsuits, kimono tops, gowns, or pajamas?

We recommend trying at least one of each to see what makes your day and nighttime routine easier and what makes your baby the most comfortable.

  • Onesies (sometimes called a bodysuit) are quintessential babywear. They’re like a shirt but with a bottom snap closure. They are usually relatively cheap, which is excellent because babies grow so quickly. They often come in cute colors or patterns, so your little one can still rock a unique style without too much wardrobe fuss. You have plenty to think about as is!
  • Kimono tops are best for minimizing contact with a baby’s umbilical cord and face. They’re excellent by themselves or as an additional easy on top.
  • Sleepers, such as gowns and pajamas, are mostly for nighttime. These are designed for your baby to sleep in comfort and provide easy changes, especially at night. The bottoms of gowns and zipper or snap based jammies make changes so much more convenient for parents and babies. Gowns are fabulous for the first few months, especially for babies who startle themselves awake when they kick their legs. You can switch to pajamas when your baby is a few months older.

2. How many do I need for each?

You can have as little or as many as you like. Newborns usually need at least one change daily because of spit ups, breastfeeding or bottle-feeding messes, and potential diaper accidents. It also depends on how much you plan to wash, the weather, budget, etc. Try one of each to find what works best for you and your baby.

3. What size should I get?

You’ll always see reviews talking about sizing issues. Within the same brand, there may be slight differences, and between different brands, it’s a little more obvious. The primary reason for this is that most baby clothing is made of cotton, which easily changes shape (read more below on cotton). Be sure to check out the sizing guide of each brand and try to buy one size bigger. If anything, you can always return the smaller product, but your baby can grow into the bigger one, or it’ll somewhat shrink in the wash to the actual size.

4. Why is organic cotton important?

Organic cotton is important for several reasons. Its natural softness is best for our baby’s delicate skin. Cotton is also a very eco-friendly material. It’s good to support the planet our children will inherit. Though cotton shrinks a little during wash, it lasts longer overall, so buy one size up!

5. What’s GOTS-certified mean?

GOTS stands for Global Organic Textile Standard. GOTS is one of the leading standard processors for organic made clothes. They monitor textiles from raw material harvesting to responsible manufacturing and end with accurate labeling for credibility. This ensures no use of synthetic fillers, AZO-free dyed, and just about everything you don’t want in your baby’s clothes.


You’re now ready to get the best babywear out there. From short to long sleeves, snaps, zippers, sleepwear, and daytime get-ups, you have all the right information to select a kind of onesie your little one will want, or maybe you’re here because you want to give one or more. Choose from all white, simple patterns, or themed designs from there. You have plenty to pick from without feeling too overwhelmed. Just remember babies are growing fast, so choose quickly with that in mind before they move a size up!
