We have tried our extenders on listed brands and we didn't come across any bodysuits that wouldn't fit one of our snap buttons, however, we can't 100% guarantee that they will fit all bodysuits as the brands might change their snap buttons from time to time. 

  1. Handmade in Australia
  2. Materials: jersey cotton, nickel-free snaps, polyester thread, calico
  3. Machine washable with like colors.
  4. Dimensions 11cm x 8cm

How to use:

Simply connect the fasteners of the Snap & Extend™ baby bodysuit extender to any suitable bodysuit and fasten as usual.  

Snaps are applied by an industrial machine, which is the most secure and durable way. We use the same snap suppliers as baby clothes manufacturers, ensuring a perfect snap. 

One extender can be used on all sizes of bodysuits. Made to best fit size 0, the extender may crease a little on smaller sizes due to a smaller spacing of the snaps (this does not take anything from its usefulness).

    Perfect Fit

    Ordering online was simple and they arrived relatively quickly in environmentally friendly packaging. I LOVED the personal thank you message for purchasing. They fit my little ones' clothes perfectly and now I can get more use out of her clothes (tall for her size). Thank you.

    excellent service and communication

    The product is superb and works on the bodysuits perfectly. The service is excellent. I noted that the products purchased were gifts for a friend, and I received an email saying that she will add a card for me. She asked me what I wanted written on it. Such a lovely gesture very impressed. Highly recommend.

    Genius idea!

    Babies grow out of their clothes so quickly! These extenders are genius and have given new life to so many singlets and undershirts for my bub. They were still wide enough it’s just the length they grow out of so quickly. One of my extenders received had a slight default, however I emailed Olga and she immediately replied and sent a new one out no questions asked! Great service and product!
