While babies are inherently cute on their own, there is something about baby clothes that can make them that much cuter. Whether dressing them like little adults or fashioning them in adorable pajamas, parents have a lot of choices for how to dress their little ones. Onesies can be a great option for a multitude of reasons.

Onesies can be more comfortable and easier to put on than other clothing options for babies. Often, they have flaps and buttons at key parts of the outfit that help parents access diapers and slip the onesie on and off. The wide variety of onesies available can be a bit overwhelming, so we’ve gone through and checked out some of the more popular options available. Here is what we learned:

Best Onesies

Editor’s Choice – Gerber Baby 5-Pack Solid Onesies

Pros: 

  • Ribbed leg opening. These onesies are designed to be comfortable for babies but also easier for parents to get a perfect fit. Not many competitors have ribbed leg openings.
  • Size options. Gerber makes this solid set of onesies for babies in more sizes that many other brands. There are 8 different sizes for various stages of baby development.
  • Available in long sleeve. Depending on the season, parents may want to get onesies that provide more warmth and have longer sleeves. This is great for those in cold climates.

Cons: 

  • Colors not available in all sizes. Those who are hoping for a particularly colored onesie may not be able to get them for all ages Pink, for example, is only available in 3 different sizes.
  • On the small side. Shoppers should be aware that some find that these onesies end up fitting a bit smaller than advertised for a particular age.

Best Patterns – Simple Joys by Carter’s Baby Short-Sleeve 6-Pack Bodysuit

Pros: 

  • Preemie size. This line of baby onesies makes their product in an especially small size that is designed for especially small newborns. Not many brands offer this small of a sizing option.
  • Overlapping shoulders. The onesie is designed to make it easy for parents to put it on, as the overlapping shoulders make it easier to finesse over the head. Great for changing in a hurry.

Cons: 

  • Not as soft as other Carter products. Those who enjoy Carter products for their softness may be disappointed. This line isn’t as soft as other offerings from Carter.

How We Picked

Baby onesies may seem simple, but for many parents, especially new parents, they can be a bit confounding when trying to pick out the best option. Whether it is the sizing, material, shape, patterns, or the sourcing of the fabric, there are many variables to sift through. Here are the aspects we weighed most heavily:

Putting them on

Though this may be taken for granted by adults who put on their clothes without thinking, baby clothes aren’t always easy to put on. Whether they are hard to get around baby’s big heads or the baby gets fussy when being put on them, onesies can be more difficult than parents expect. Brands have methods of mitigating against this problem.

Some brands make their fabric more flexible, either through how they treat the fabric or how they knit it. Another method is by making the shoulders overlap, so as to be able to slip a wider body through. Buttoned flaps can also make putting on a onesie a bit easier.

Design

The sheer variety of different patterns and designs available in onesies is something to marvel at. From animals to vegetables, trucks, and planets, the subject matter featured in onesies can cover a wide range of imagery. Parents have a lot of choices that can be everyday wear or reserved for special occasions and holidays.

Parents will typically shop by theme; onesies come in packs that revolve around a certain baby-based topic. The individual onesies will be very diverse within the pack, all with unique designs. With just a few packs, parents can have a lot of versatility in patterns, imagery, and colors.

Fit

Often times, clothing doesn’t fit as we expect it. The same thing goes for baby onesies. Sizing can be too tight or too baggy, so it is important to pay attention to specific dimensions.

Brands typically offer onesies in three month increments (0-3 month, 3-6 month, etc.), though some have sizes for smaller newborns, and some even for premature babies. Parents can buy several different sizes to see which fits best. How the onesies react to being washed can be a pivotal factor as well.

Tips

Not sure which baby onesie is right for you? Here are some tips that can make the process a bit easier:

  • What age is your baby? 
    • If your baby is on the cusp of one age range, it may be appropriate to buy a size larger. As the onesies tend to be for every 3 month increment, babies may size out of their current onesie quickly.
    • Certain products will not be sized appropriately based on how they are advertised. Pay attention to specific dimensions and the materials they are fashioned from.
  • Is this for an occasion?
    • Parents can have fun styling their little ones for certain events and holidays, or even for seasons. Those who love certain sports, motifs, or color schemes are sure to find a onesie to fit their tastes.
    • Be careful not to go too heavy on themes; each pack usually comes in packs of  three, five, or seven. That means parents will have an abundance of a certain theme by just getting one pack.
