Newborn onesies are a staple item on baby registries around the world. This classic one-piece outfit is timeless and works for every occasion. Whether dressed up or dressed down, onesies are an essential part of a baby’s wardrobe. 

Over the years I’ve used what seems like hundreds of onesies. With five children, I’m always looking for ways to make dressing the baby simple. Onesies are the perfect solution. 

Each time we’ve brought home a new baby, I’ve made sure we’ve had a stockpile of onesies. Between diaper blowouts and spit-up stains, we go through plenty. 

Through the years, I’ve found that not all newborn onesies are created equal. 

I’ve purchased onesies that faded quickly or stretched out at the collar. I’ve also had onesies that ran extremely small or big. We’ve learned which brands we can trust for a quality, durable onesie that will last. 

If you’re shopping for cute, high-quality onesies, look no further. I’ve made a list of the best onesies that are sure to please. Your little one will look adorable with any of these picks!

Of all the baby outfits I’ve purchased through the years, some of my favorites have been by Carter’s. When you purchase a Carter’s outfit, you know exactly what quality you’re getting. The Simple Joys by Carter’s Short-Sleeve Bodysuit is no exception. 

This 6-pack of onesies comes in adorable prints and fun colors for both boys and girls. I picked a set with solid colors including pink, blue, and gray for my newborn girl. The solid colors make it easy to throw with any bottoms if I choose.

I have noticed that not all onesies come in sizes for preemie babies. This set starts at a preemie size and goes all the way up to 24 months. They also fit true to size.

Even after several washes, Carter’s clothes don’t wear out easily. These onesies are soft, and the same high quality that I would expect from Carter’s. 

The lap shoulders make it easy to take the onesie off from the top down for diaper changes. All of the edges are reinforced and include an adorable scallop detail. The snaps feel very secure and are made without nickel in case of allergies.

I’ve purchased these onesies many times over the past decade, and can honestly say they are the best baby onesies on the market. The only drawback is that some of the onesies in the set have snaps on the back. If you’d like to avoid those, you’ll want to look carefully and choose a set that doesn’t have them.

Every parent knows the brand name Gerber. Gerber remains one of the most trusted brands in baby products. The Gerber baby-girls 4-pack Short Sleeve Onesies are just as reliable as the brand itself. 

I’ve bought plenty of Gerber baby clothing throughout my motherhood journey. While they aren’t always the most luxurious clothes on the market, they’re always durable and affordable. I grabbed this 4 pack of cute onesies so I would have weekday outfits that can get dirty. 

Gerber baby onesies, 4 pack.

I love that there were so many patterns and colors to choose from. These come in both girl and boy sets. They’re also affordable and of great quality for the price point. 

One thing I’ve always noticed about Gerber onesies is that they tend to run small. If you’ve never purchased Gerber baby clothes, you might want to size up to be safe.

These have expandable lap shoulders and bottom snaps for easy diaper changes. They usually fit snugly and aren’t as easy to undress from the top down as others. However, it’s not so difficult that it would deter me from buying these again.

Best Sleeveless: Hudson Baby Unisex Baby Cotton Sleeveless Bodysuits

Hudson Baby Unisex Baby Cotton Sleeveless Bodysuits
  • Set includes coordinating sleeveless bodysuits
  • Made with 100% cotton
  • Soft, gentle and comfortable on baby’s skin
  • Optimal for everyday use
Pros
Cons
  • Cute designs
  • Breathable cotton
  • Snaps at the bottom
  • Shrinks considerably

When warm weather hits, I’m always on the hunt for cute summer baby clothes. The Hudson Baby Unisex Baby Cotton Sleeveless Bodysuits are some of the cutest sleeveless onesies I’ve found. 

These come in both boy and girl designs in a set of 5. From mermaids to baseballs, there’s something for everyone. The style of the straps varies depending on which you choose.

I love that the sets for girls include ruffles on the straps. These onesies are great beach essentials for baby to pack on your next trip to the shore. They’re made with 100% cotton, so they won’t irritate baby’s skin in the heat of the summer.

These do have snaps at the bottom but don’t include an expandable neckline. However, since they don’t have sleeves, they should still be easy enough to undress from the top down. The thicker straps on the boys’ onesies might be trickier. 

Some parents noted that these shrunk considerably in the dryer. They will likely still stretch to fit, but sizing up might be a good idea.

Burt’s Bees makes buttery soft baby clothes and accessories. They also make some of our favorite non-slip baby socks. The Burt’s Bees Baby baby-boys Bodysuits, 5-pack does not disappoint. 

If you’re looking for baby clothing that won’t irritate the most sensitive skin, this is for you. The cotton is ultra-soft and won’t pill after washing. It’s also GOTS-certified and 100% organic. 

If you’re worried about your baby overheating at night or out in the summer heat, you’ll be happy to know the organic cotton is breathable and cool. They offer both long-sleeved onesies and short-sleeved onesies in a 5-pack. You’ll also be able to purchase sizes from preemie to 12 months.

These don’t come in as many prints and colors as I’d like. However, the price is fantastic and they would make great weekday clothes. They also hold up in the washer and dryer. 

All of these soft onesies have lap shoulders and bottom snaps. Undressing the baby is relatively easy with the size of the neck opening.

Overall, for super-soft, organic baby clothes, you can’t beat the price and quality of these onesies.

Best Stretch: Hanes Ultimate Flexy Sleeveless Bodysuits for Boys & Girls, 5-pack

Hanes Ultimate Flexy Sleeveless Bodysuits for Boys & Girls, 5-pack
  • SHOP LESS, SPEND LESS – Get more growing time from each size. Size 0-6 fits 0 – 3 months AND 3 – 6 months; 6-12 fits 6 months, 9 months AND 12 months; 12-18 fits 12 months AND 18 months, 18-24 fits 18 months AND 24 months.

Pros
Cons
  • Super stretchy fabric
  • Sizes that last longer
  • Lap shoulders
  • Not many patterns to choose from

If you want a newborn onesie that will make diaper changing a breeze, this is for you. The Hanes Ultimate Flexy Sleeveless Bodysuits for Boys & Girls, 5-pack is a set that provides serious stretch.

I’ve mentioned the lap shoulders quite a bit already, but there’s a good reason for it.  Expandable shoulders allow you to slip the onesie off the baby’s shoulders and pull it down over the baby’s diaper. This keeps you from having to pull a dirty onesie over the baby’s head after a diaper blowout.

Hanes has created some of the best baby clothes for messy diaper changes. The expandable shoulders and ultra-stretchy fabric will allow you to easily undress your baby. This is the perfect option for the early newborn days. 

Hanes offers both boy and girl varieties that come in packs of coordinating colors.

You won’t find many designs other than basics like shapes or stripes. Most of the baby onesies are solid colors. However, I appreciate the solid colors in the pack because they are easier to match with bottoms. 

The sizing is different than most, due to the stretchiness of the material. Your baby will be able to wear the onesies for longer than normal. The sizes range from months 0-6, 6-12, 12-18, and 18-24.

Honest Baby is serious about offering products that are safe for your family. The soft organic cotton they use is GOTS-certified and made without heavy metal phthalate dyes. They even ensure that the bottom snaps are nickel free.

The patterns and colors are trendy and cute. Some packs include all solid colors, while others have a few patterned onesies mixed in. They range in size from preemie to 24 months.

These are a bit expensive compared to other options. However, they do hold up well in the wash and may be worth the extra expense for soft organic cotton. Other organic onesies I’ve shopped for don’t have as many color options.

Unfortunately, these don’t come in preemie size. You’ll only be able to choose from newborn to 12 months. It would be nice if the sizes expanded from preemie to 24 months. 

As I mentioned earlier, Gerber baby clothes tend to run small. Their newborn onesies, for example, only fit from 5-8 lbs. So you might want to size up.

I love the hilarious sayings many of the onesies have like, “Don’t look at me, that smell is coming from my dad”. There’s also a wide selection of sentimental sayings for firstborns or babies’ first milestones. The sayings bring more fun to your baby’s outfits. 

Each onesie is made with cotton and includes lap shoulders and bottom snaps. When purchasing, you can choose your favorite saying, but can’t specify the color of the fabric. 

Unfortunately, there is only one long-sleeved onesie to choose from. So these are a better option for short sleeve onesies. For a warm-weather option, they are breathable and soft.

The sizing starts at 0-3 months and goes up to 12-18 months. So these make a perfect gift for both babies and toddlers.

Pros
Cons
  • Trendy floral patterns
  • Tassels and ruffles
  • Headband included
  • Hand wash for best results

As a mom of 5 girls, I love baby clothing with all the frills. The Hascloth Newborn Baby Girl Romper is the perfect onesie for little girls.

There are eight short sleeve onesie styles to choose from. Each comes in a trendy floral pattern, with the exception of one watermelon print. These onesies are adorable and include tassels around the legs. 

My favorite feature is the ruffle trim down the sides. It just adds character to the onesie while dressing it up. The onesie also includes a matching headband. 

Hascloth uses a blend of polyester and spandex for the fabric. While cotton is usually the desired fabric for baby onesies, this blend is a better choice for a dressy onesie like this. 

The sizes range from 0-3 months to 12-18 months. It would be nice to see preemie, newborn, and 18-24 months offered. 

You’ll want to hand wash and line dry this item, as the tassels won’t hold up well in the washer and dryer. This would be more of a special occasion onesie than for everyday wear.

Recommended Accessories

The great thing about a short or long sleeve onesie is that you can layer it in colder weather or add accessories to dress it up. Here’s what I recommend for dressing your baby along with a onesie:

Reasons Why Babies and Moms Love Onesies

Baby sleeping on white fur with stuffed animal.

It’s no secret that moms love onesies for babies. They’re one of the most popular items of clothing for little ones. Why are they so popular?

Here are a few reasons why: 

  • One piece outfit 
  • Easy to change baby in
  • Perfect for play 
  • Snug fit that’s comfortable for baby
  • Cute patterns and colors
  • Won’t irritate the umbilical cord stump

Is it okay for babies to sleep wearing a onesie?

Most people think of footed pajamas with long sleeves when it comes to dressing a baby for sleep. However, onesies are a perfect option for sleep. You’ll just want to be sure your baby is warm enough. 

In cooler weather, try layering the onesie under a baby sleep sack to ensure they are warm enough. In the summer, a onesie under a light swaddle might be warm enough. 

FAQs 

When should babies stop wearing onesies?

If you’re asking yourself, “When do babies stop wearing onesies”, the answer is really up to you. There are several reasons why parents choose to keep onesies in their child’s wardrobe for longer than others. This might be for easy access for diaper changes or for comfort. 

When you decide to stop purchasing onesies is up to you. Generally speaking, most companies make onesies up to size 24 months. This is the average age children start potty training

How many onesies does your baby need?

If you’re making your newborn checklist, you’ll want to include plenty of onesies. Babies often have diaper blowouts that require a change of clothes. Since laundry can be hard to keep up with after a new baby, I like to have around 14 to keep from running out.
