If you’re shopping for your little one’s clothing, you might be interested to know the difference between bodysuits, jumpsuits, rompers, sleepers, onesies, and other types of baby clothes.
Today, we’ll help you understand the modern names of baby clothing. After reading this article, you’ll have a better idea of what to purchase for your newborn.
Bodysuits for newborns and their variations
Baby bodysuits are a type of modern clothing that resembles a shirt or a t-shirt, fastened with snaps between your little one’s legs.
It’s very convenient, as unlike the old-style snap-front shirts, this clothing won’t ride up or twist, ensuring your baby’s warmth and comfort.
Bodysuits are often used as pajamas, at home or outside. This versatile clothing item should be a staple in every newborn’s wardrobe!

We recommend purchasing several different versions of these baby bodysuits to understand which one is best suited for your little one:
- Bodysuits with scratch mittens – the ideal solution for the smallest babies who may accidentally hurt themselves. The end of the sleeve will have a mitten-like cover that will hide your baby’s hands. That’s why they are also often called bodysuits with closed sleeves for newborns.
- Long-sleeved bodysuits – the optimal option for cool weather when you need to additionally warm up your baby.
- Short-sleeved bodysuits for newborns – perfect for warm weather when you want your baby’s body to breathe freely and not overheat under layers of clothing. It is made in the form of a tank top or a T-shirt with short sleeves.
In addition to the styles listed above, there are also models that differ in type:
- necklines: it can be round or in the form of a small stand-up collar;
- fasteners: here, parents can choose options with buttons, snaps, ties, and even items with zippers;
- placement of fasteners: between the legs, on the shoulders, diagonally from the neck to the legs, etc.
Newborn jumpsuits, onesies, and rompers
Don’t know the difference between a onesie and a jumpsuit? Or what newborn rompers are? Let us tell you a little secret: they’re all the same thing.
Jumpsuits are comfortable, functional clothing that cover a baby’s arms and legs, but don’t restrict their movements. It’s like a little suit that covers the entire body of the tiny human. That’s why this item of clothing is often called a “human” in Russian: it’s simple and understandable!
In these outfits, your little one will be comfortable exploring the world around them. And they’re also very comfortable to sleep in, which is why they’re often called “sleepsuits” in English. They’re like pajamas for babies, where nothing restricts their movements and allows them to have a healthy rest.

To make it even clearer, here’s how a onesie is different from a newborn jumpsuit:
- A onesie is a bodysuit that fastens between a baby’s legs.
- A jumpsuit or romper for newborns is a top that’s connected to the bottom in one piece.
This type of clothing for babies can also fasten at the front or back with buttons, ties, or a zipper, and can have open or closed legs/arms.
What are rompers and jumpsuits for newborns?
A baby romper is the same thing as a jumpsuit for newborns. The thing is, recently many online stores have adopted the trend of calling well-known items in a foreign way.
If you come across a model that looks like a T-shirt (less commonly a tank top) that transitions into shorts, then know that it’s a romper for newborns.
Sometimes instead of shorts, a baby romper can have capris or pants. Typically, this item of clothing is taken for infants or children up to two years old.
Jumpsuits can be used both as home clothing and as sleepwear or for a walk.
When choosing rompers, bodysuits, or jumpsuits, take items one size larger if you plan to wear a diaper underneath.

Regardless of what you choose, pay attention to:
- The material that was used to make the item. Things made from quality knitwear are preferred. This choice is due to the fact that this fabric allows air to pass through well and absorbs moisture, maintains proper heat exchange, and does not cause irritation, redness, or allergies.
- The cut. Pay attention to the quality of the pattern, thanks to which the clothing fits well and does not restrict the baby’s movements.
- The fabric’s density. Choose clothes according to the season. This way, your little one won’t get cold or overheated.
