The Onesie Extender


In Stock

100% Money Back Guarantee + Free Returns

Sometimes our little ones grow faster than their clothes can keep up. Rather than picking up a new set of onesies, try these onesie extenders! This revolutionary product is so simple but such a game changer. Like all of our products, this uses high-quality material that has been parent-tested and approved. 

These extenders not only extend the life of your favourite onesies, but of your wallet as well by eliminating the need to replace good condition clothing just because it's too short. 

Main Benefits:

  • Go from "None of these fit!" to "All of these fit!" with a single extender that can be used on countless onesies 
  • Just a few snaps and adding, swapping and removing the extenders  is a breeze
  • Selection of colours means you can coordinate with the clothes you already have


We all have our favourite onesies, whether it's the cute pattern, the nice wide neck or the perfect colour that hides every yogurt stain, but sometimes we don't get much time to show them off. They can hit a growth spurt the minute we clip the tags and perfect condition tops end up in the "Donate" box. With this simple fuss-free product, you can give extra life to those and many other onesies. With our easy online store, you can browse with confidence knowing any necessary returns or exchanges are quick and painless.
