Size Guide

Back in stock mid-October

This Snap & Extend baby bodysuit extender fits only Jamie Kay brand.  NOT COMPATIBLE with the latest Jamie Kay collection Forever floral and Pointelle collection of bodysuits (our extenders with 10 mm button are compatible with those). NOT COMPATIBLE with the relaxed fit (no JK tag on the side) and new essential collection. We advise you to get our sample buttons to try it first before purchasing.

You might need our extender with 9 mm or 10 mm buttons. See the size chart for compatible brands. To reduce waste if you purchase more than one extender, we place two extenders into each packaging.  (Would you prefer to wrap them separately, let us know in the comment section in your shopping cart)

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).

    All good things

    These are fantastic, so practical. My babies have both been much taller than they are round so it great to be able to extend the life of body suits. Also great for wrapping around bulkier clothes nappies for car trips etc and they prevent wicking.

    Fits so well!

    The extenders have really helped a lot. My baby has been growing so quickly that there were some pieces of clothes only being used once or twice. The 8mm extender has really helped especially since some of the clothes were from relatives overseas and have sentimental value. Thank you so much for making a great product!

    So handy

    Really love these as they make those overpriced body suits I just couldn’t resist a whole lot palatable on the purse.

    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!
