Here are 17 great onesies to consider.
Star Wars Short-Sleeve 5-Pack Onesies
Best Star Wars Baby Onesie
If you or your partner are Star Wars fans, these onesies are sure to be your favorite baby clothing items.
Choose from three sets of five onesies to suit any baby rebel. The fabric is a cotton and polyester blend, so it’s warm but breathable.
The expandable lap shoulders make it easier to dress your little one.
Although these are labeled as onesies for boys, there’s no reason your little girl wouldn’t look just as adorable in a “Little Trooper” or Wookie design.
My experience with these adorable outfits has been nothing short of delightful, as they've added a fun and nerdy touch to my baby's wardrobe. The quality feels durable, and the sizing was spot-on, allowing my little one to grow comfortably into the 18-month clothes. I appreciate the variety of designs available, but would love to see more options featuring female characters like Princess Leia or A'soka in the future.

Babysoy Organic Baby Onesie
Best Animal Baby Onesie
A cute animal print makes any piece of clothing ten times sweeter. This one is made of an ultra-soft cotton and bamboo blend.
The lightweight material works for dressing your baby in summer on cooler days, but it’s warm enough for winter wear and makes a great layering top. The long sleeves are suitable for chilly evenings.
The onesie is available in six unique and adorable animal prints, such as a rabbit, chimp, or wolf.
Got these adorable onesies and was impressed by their high quality fabric and cute animal designs. The sizing can be a bit inconsistent, so I recommend getting a size up for your child. These onesies are incredibly soft, thanks to the organic cotton and azlon blend, and it's great knowing that part of the proceeds go to the Jane Goodall Institute. They wash well, maintain their softness, and have no irritating tags, making them a fantastic addition to my baby's wardrobe.
Babiy Logic Onesie
Best Nerdy Baby Onesie
If you’re a nerd at heart, you probably want your legacy to live on in your baby. This onesie comes in your choice of pink, white, or blue and has a programming code design.
The fabric is high-quality, 100% cotton, and the print is made with highly durable ink to survive multiple washes.
This onesie would make an adorable gift for programmer parents!
I'm quite pleased with this onesie as a gift for my programmer friends who recently became parents. Although the design is adorable and the quality is decent for the price, I found that the sizing runs quite small. I initially purchased the 6-month size, but it seemed more like a newborn size, so I recommend sizing up. While it's not the best quality on the market, it's still a cute and thoughtful gift that the proud parents absolutely loved. Just keep in mind to order a larger size to ensure a good fit for the little one.
Burt's Bees Baby Unisex Baby Short-Sleeve Bodysuits
Best Organic Baby Onesie
What’s better than organic clothing for your little one? Burt’s Bees has you covered — especially if your baby is prone to skin irritation.
If you want something sweet, stretchy, and breathable — these 100% cotton onesies are ideal. And the fabric is almost as soft as your little one’s skin.
There are five adorable sets to choose from, each containing five bodysuits made by our favorite natural product creators.
These adorable Burt's Bees baby products made the perfect decor for a recent baby shower I attended. Not only was the quality top-notch, but the price was also a great deal. I've purchased this for multiple friends' baby showers and even for my own baby, who was on the smaller side, and the soft fabric and accurate sizing made it perfect for him. The variety of patterns available and the soft, comfortable material make these an essential item to have on hand when welcoming a new baby. The grandparents absolutely loved these as a gift, and I can confidently say that they were a hit at the baby shower.
Disney Baby Boys' Mickey 5-Pack Bodysuits
Best Disney Baby Onesie
Disney is a magical world — not only for kids but also for adults.
Return to the classics with these adorable Mickey and Minnie printed onesies. Or choose from one of seven other sets with characters like Winnie the Pooh, The Lion King, or a combination of other Disney favorites.
These bodysuits are made from a cotton and polyester blend, and the machine-washable prints don’t fade or run.
These Winnie the Pooh shirts boast great quality and adorable designs, perfect for dressing up or down for little ones. I found them to be lightweight yet not see-through, holding up well during our trip to the parks. They fit true to size and have remained durable over time. Although the lavender shirt may seem more suited for a little girl, the overall charm of these shirts is undeniable. Fast shipping was a bonus, making them arrive just in time for our Disney adventure.
O2Baby Organic Cotton Onesie
Best Thick Baby Onesies for Winter
Keeping your little one warm is crucial. For colder weather, you might consider a long-sleeved onesie with legs.
This onesie is fitted with a zipper that runs down the front and legs, making it easy to put on and take off or open for diaper changes. Made from an organic cotton and spandex blend, it will keep your baby cozy even on the coldest nights.
The jumpsuit is available in a variety of colors and prints and sizes from newborn to 18 months.
If you're looking for a comfortable and practical outfit for your baby, this sleeper is a great choice. I found it to be soft, easy to put on, and perfect for everyday use around the house. The fold-over cuffs helped prevent my baby from scratching herself, and the organic cotton material was gentle on her sensitive skin. However, be aware that the fabric is not preshrunk, so it's best to hang dry it after washing to avoid shrinkage and maintain the proper fit of the zipper. Additionally, the color options are somewhat limited, but the designs available, like the cute strawberries, are still adorable.
Moon and Back Baby Set of 5 Organic Long-Sleeve Bodysuits
Best Soft Baby Onesies
When you put your baby down for the night, it’s always good to know they will be comfortable. Long-sleeved onesies are good for chilly nights — or days. The fabric on these onesies is softer, thicker, and warmer than many other brands, so you know your little one will stay warm and cozy.
These sweet and simple bodysuits are made from breathable, 100% organic cotton. We love that they come in gender-neutral colors that aren’t just the standard plain yellow and green.
After trying various brands, I have to say that these onesies are my favorite. They have a thicker and softer material than most, making them perfect for cooler weather or when the air conditioning is on. The fit is true to size and they hold up well in the wash, even on high heat. The seams are a bit different from other onesies, but they don't affect the overall quality and comfort of the garment. These onesies are a bit pricier than some alternatives, but the premium feel and durability make them well worth the investment.
Hudson Baby Cotton Long-sleeve Bodysuits
Best Cheap Baby Onesies
If you want to save money but don’t want to compromise on quality, these sets boast thousands of positive reviews and cost less than many other brands.
Choose from dozens of adorable prints to suit any style, all in a warm but breathable 100% cotton material that lasts through countless messes and cleanings.
These onesies come in sizes from newborn to 24 months, keeping you coming back for more when your little one hits a growth spurt. However, the sizing is quite generous, so if you need them to fit right away, don’t buy a size up.
In my experience, these onesies have proven to be a great purchase for my 17-month-old. The soft and slightly stretchy material makes them comfortable for her to wear, even though they are a bit large on her right now. I've found them to be perfect sleep shirts, and the cute designs are a bonus. However, I did notice some inconsistency in the tailoring, with the leg holes varying in size between different onesies. Despite this minor issue, I still find them to be a good quality and affordable option for baby clothes.
Tstars You Can Do This Dad
Best Funny Baby Onesie
Baby clothes are not always easy to figure out. If your partner, like mine, finds it difficult to dress your baby without supervision, this humorous onesie guide is a great idea!
The onesie has expandable shoulders for easy dressing, saving tears from baby and daddy. It’s also made with 100% cotton and can be purchased in blue, pink, or white.
My experience with this onesie has been nothing but positive and entertaining. The gender-neutral colors make it a versatile gift for any expecting parent and it can even be passed down to future siblings. It's a bit large for a newborn, but that just means it will last longer as the baby grows. The fun and humorous design brought smiles, giggles, and even became part of a baby shower decoration, making it a memorable gift. Although the wording might be considered a bit sexist, it still served its purpose in including first-time dads in the celebration.
Gerber Unisex Baby 5-Pack Short-Sleeve White Onesies
Best Plain White Baby Onesies
Crafty mamas might enjoy customizing their baby’s clothes with fabric markers, tie-dye, or Cricut designs.
Or maybe you’re just practical and want something pure and simple or for layering purposes. This set is ideal if you are a “team green” mom-to-be.
These cotton onesies have double-stitched hems that will survive wash after wash. One thing to note is that they may shrink a little with washing, so buying a size larger could ensure they fit longer.
I recently purchased these onesies for my 3-year-old son and they have been a fantastic solution to a problem we were facing. Not only have they helped break his habit of reaching into his diaper, but the fabric is soft, stretchy, and durable. I've used these onesies for tie-dye projects and custom t-shirt creations, and they've turned out beautifully. They fit taller and bigger kids, making them a staple item in our household. Plus, they stay in place when picking up your little one, unlike regular t-shirts that ride up and need constant readjustment.
Little Treasure Baby Cotton Bodysuits
Best for Christmas
Tacky Christmas sweaters are a must-have. But if you want something cute for your baby to wear this Christmas that isn’t made of scratchy knit material, check out these adorable onesies.
They come in packs of three, and there are several Christmas designs to choose from, as well as other choices. We like the “Santa Baby” for girls, and this set is our favorite for boys.
The long-sleeved onesies have a wide-neck opening to fit over even the biggest noggins easily.
In my experience, these onesies offer vibrant colors and impressive durability even after multiple washes. I noticed that the sizing runs true, with only a slight difference in torso length between the 12-18 month and 18-24 month sizes. Despite one instance of a sleeve detaching, I found the overall design and softness of these onesies to be absolutely adorable and great value for the price.
Luvable Friends Baby Cotton Bodysuits
Best Unisex Baby Onesies
If you don’t know whether you’re expecting a boy or girl, you might consider unisex clothing, which is also practical if you’re thinking of future siblings. And with so many color options, you don’t have to stick to only white.
These adorable Luvable Friends onesies are made from soft cotton. Many other color options are available, all in sizes up to 24 months.
These onesies caught my attention with their vibrant colors, patterns, and soft material that can be used for both baby girls and boys. My personal experience includes using them to make personalized onesies for my son, and they held the vinyl perfectly. However, I did notice some inconsistencies in sizing, as they seemed to run big and shrink after washing. I recommend opting for a size bigger to allow some wiggle room, as I did with the 18-24 month size for my 14-month-old grandson.
Warner Brothers Justice League Bodysuits
Best Superhero Baby Onesie
Superhero designs are so fun for babies. These onesies are made from a cotton and polyester blend — soft and breathable — ready to take flight. And the overlapping shoulders and snap closures will help to make those superhero diaper changes even quicker.
Daddy will love showing off his new little man in any of these colorful onesies. And if you have a little heroine, you will love this set for girls.
I'm quite pleased with these shirts as they are not only soft and well-made, but also fit a bit bigger than expected. My 20-month-old son can still wear the 12 to 18-month size comfortably, and they have a cute design that makes them stand out. While they may not be suitable for a newborn's first outfit, they're still a fantastic purchase for slightly older infants.
Baby Thanksgiving Onesie Outfit
Best for Thanksgiving
Thanksgiving is a time for us to be grateful for everything we have and all the love we share. Here’s another thing to be grateful for — a chance to dress your little one up in a seasonal outfit.
When visiting friends or family, why not dress your baby in an outfit that reads “Daddy and Mommy’s Little Turkey!” The four-piece set is made of a cotton blend and includes a romper, pants, hat, and matching headband.
I recently purchased this outfit for my child's first Thanksgiving, and I found it to be quite versatile, as it includes both a hat and headband to accommodate either a boy or a girl. The outfit was comfortable and received many compliments, but be aware that it may run large and the sizing for individual pieces can vary. The material is on the thinner side, so adding a jacket might be necessary depending on the weather. While the colors are festive and fun, the quality of the workmanship could be improved, as some pieces showed signs of wear after washing.
Kewlent 3Pcs/ Outfit Set
Best for Halloween
Our favorite time of year is when we can dress up in silly Halloween costumes and use our kids as an excuse to eat insane amounts of candy.
If you’re not into fancy dress-up clothes, you might like this brightly colored pumpkin outfit. The style and color would suit a boy or girl, and it includes a pair of pants and a matching hat, with the onesie reading “My First Halloween.”
The three-piece outfit consists of a long-sleeved bodysuit, pants with an elastic waist, and a matching hat.
After purchasing this Halloween costume for my baby's first Halloween, I was thrilled with its cuteness and perfect fit. The fabric was just right, not too thick or thin, and the quality was great for the price. However, I noticed the material was a little stiff and thin, so be cautious when drying it to avoid the letters sticking together.
AW Fashions One-Piece Baby Bodysuit
Best Vulgar Baby Onesie
A good list wouldn’t be complete without a little naughtiness, right? Whether you want something for your child or you need a sassy baby shower present, this onesie checks all the boxes.
The pure cotton fabric is stretchy, and the print is made with durable ink to last through multiple washes, so your little one can wear it everywhere you’d like to make a statement.
My experience with this baby gift has been nothing short of delightful, and it was a definite hit at the baby shower I attended. The humor behind the design brought smiles to everyone's faces and sparked conversations among the guests. I found the quality to be good, although the length seemed a bit too long for a newborn. While I can't speak for the sizing, I know that my friend, who is expecting a baby in April, absolutely adored the gift. This amusing gift not only provided laughs, but it also created cherished memories for the soon-to-be parents.
What’s the Best Material?
When choosing onesies, you want to choose a material that is suitable to the climate but also soft and comfortable, as your baby’s skin is sensitive.
We always recommend cotton for baby clothing. It absorbs moisture, keeping your little one dry. It’s also gentle on the skin and less likely to trigger any reaction.
If you can’t find pure cotton, look for a blend that includes polyester, spandex, or bamboo. These are also breathable and much easier to care for.

How Many Onesies Do I Need?
Babies spit up and have poop explosions, and don’t forget about spilled milk. We recommend starting with a minimum of four to seven pieces, although if you’re hoping to space your laundry days out a little, or if your little one tends to be extra messy, you may wish to extend that number.
Sizing Tips for Onesies
It’s impossible to predict how big your baby will be or how fast they will grow once they’ve arrived.
Below is a quick guide to the sometimes confusing world of baby sizes. Of course, the sizes are approximate and will vary, depending on the manufacturer and product.
- Newborn: Generally, this size fits babies weighing up to 7 pounds. If your ultrasound shows you might have a big baby, you’ll want to skip this size.
- 0-3 months: 7–12 pounds, up to about 23 inches. Some babies may even skip this size.
- 3-6 months: 12–17 pounds, up to 27 inches.
- 6-12 months: 17–22 pounds, up to 29 inches.
- 12-18 months: 22–27 pounds, up to 31 inches.
Don’t stock up on newborn sizes, and don’t waste your money on preemie clothing unless you know your baby will arrive early.
If you want to get newborn sizes before your baby arrives, choose three or four pieces only. Size 3-6 months is the best size to stock up on before birth. Once your baby is in your loving arms, decide for yourself when you need bigger sizes (1).
How to Wash Baby Onesies
Start by reading the label. We highly suggest checking this before purchasing to make sure the items don’t have any special wash requirements.
When changing your baby, you’ll need clean clothes fast, and who has time to care for a newborn and wash onesies by hand? Separate everything by color as you usually would, and use a mild, perfume-free detergent.

Do Newborns Need Long Sleeve Onesies?
Newborns may need long-sleeve onesies, especially in cooler temperatures, to keep them warm. Their ability to regulate body temperature isn’t fully developed yet, so layers can be crucial.
Do Babies Wear Onesies Under Swaddle?
Yes, babies can wear a lightweight onesie under a swaddle. It offers an extra layer of warmth and can prevent any chafing from the swaddle material.
Do Newborns Need Pants Over Onesies?
In cooler weather, adding pants over a onesie can provide additional warmth. However, in warmer conditions or indoors, a onesie alone is often sufficient.
