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).

    Great buy!

    Glad to have come across the bodysuit extenders last year at the baby expo! And so happy to see some JK extenders, too! Definitely recommend these! Quick shipping and great service. Keep up the amazing work Olga! :)

    Love it!

    Best thing I did was get a JK extender. Now I don’t need to upsize all my $30 jumpsuits, which would become very pricey!
