A] Difference Between a Onesie, Sleepsuit, Bodysuit, and Romper

First-time parents often have too many questions (and rightly so) when it comes to buying clothes for a newborn baby. Can you put a bodysuit under a sleepsuit? Should the baby always wear a bodysuit even while sleeping? What is the purpose of a romper? If you too have these questions, then below is a breakdown of each piece of baby clothing alongside its advantages. You can also refer to our guide on choosing the most suitable clothing for babies to make the right purchases.


    A onesie is a one-piece garment for babies with a top that is fastened with poppers and fits over the baby’s nappy. It has no legs but long or short sleeves. It can be worn under a baby suit in cold weather or as a complete outfit in warm weather. Onesies are also called diaper shirts or snap suits. Baby onesies are popular for both baby girls and boys and come in numerous designs and patterns. Compared to a t-shirt and shorts, a onesie is more practical as it stays tucked in and does not ride up, thereby keeping the baby comfortable.

    The advantages of buying a onesie for your baby:

    • These are very comfortable and stay in place even when the baby moves around
    • A long-sleeve onesie provides an excellent base layer for the winter
    • A short sleeve onesie is perfect airy casual wear for the summer

    Note: Onesies are available for kids till the age of 3. At three years, most kids are potty trained, so a onesie wouldn’t be a practical clothing option beyond that.


      A sleepsuit is essentially like a Babygrow. Sleepsuit and Babygrow are one-piece suits that cover both arms and feet. It is pyjama style clothing that comes with or without feet. Some sleepsuits have zippers, while others may have buttons and ties. A sleepsuit makes a perfect outfit for a day out!

      Some of the advantages of a sleepsuit are:

      • Sleepsuits are available in different shapes, sizes, designs and styles.
      • Most sleepsuits are made from baby-friendly soft materials i.e. fleece or cotton. So your baby is comfortable all day long.
      • Sleepsuits can be worn in all seasons, are easy to wash and dry, do not include hazardous sharp edge designs or buttons. This ensures complete safety, increasing its functionality.


        A bodysuit is a one-piece stretch garment worn by babies. It is like a t-shirt with an extension below the waist and can have long or short sleeves or no sleeves at all. They are designed with keeping comfort and flexibility in mind and are often used as sleepwear for babies. Baby bodysuits have poppers at the bottom to make it easy to remove them while changing diapers. Plus, they can be worn in summer and winter.

        The advantages of a baby bodysuit are:

        • They are a comfortable clothing option for babies and easily washable
        • They are usually made from soft, fine cotton, which protects the baby's sensitive skin
        • It protects the top layers of clothing from stains (in case of a leak)

        4. BABY ROMPERS

          Rompers are one-piece garments/outfits that are easy to put on and remove. They have sleeves and short legs and are closed using zips, buttons, or snap fasteners. A romper can be worn as a pyjama or as a complete outfit. Other names for rompers are romper suits, jumpsuit, playsuit, and baby pyjama.

          Rompers are incredibly cute and can be worn during the day or at night. Short-sleeve and short-legged rompers are a good choice for a play date in the warm weather as they cover the baby without affecting functionality while being light and keeping your baby cool.

          They have fasteners along the inside of the legs, which makes it easy for parents to change diapers without taking the entire outfit off. Baby rompers come in numerous sizes, from preemie baby to newborn to toddler. Even older children wear rompers in place of pants and a T-shirt. 

          The advantages of wearing a romper are:

          • They provide easy access to diaper change
          • Some rompers have build-in socks
          • Most rompers are made from cotton. This makes it easier to wash baby clothes.
          • Short-sleeve rompers are a complete one-piece outfit that can be worn during the summer season

          Note: It is better to avoid rompers with built-in feet for toddlers as they can be slippery on hard floors.
