Apart from the dimensions above, these are the things to consider in choosing the size that will perfectly fit you:

  • Style – Onesies come in footless and footed style. This is a main set back for those getting the footed onesie, you need to know if the onesies will fit the length of your feet aside from your height. You can also use the size of your shoes as reference when buying footed onesies. On the other hand, it is easier to purchase a footless onesie because you can just hike it up or down depending on the length of your extremities.
  • Fabric- You must be knowledgeable of which fabric shrinks or not. Be cautious in washing your onesies to avoid shrinkage and discoloration.
  • Always choose one size larger if your body measurements fall between two different sizes.
