Our styles have been carefully sized and scaled with reference to the most commonly shopped mainstream brands. However, our children come in all sorts of beautiful shapes and sizes, so often a simple age banding doesn't give you all the info you need to be sure a product will fit.

On this page we've shared the key measurements for each size, to help you be sure you've got the right fit for your little one.

All measurements are in cm, unless otherwise indicated.

Chest width is taken from just underneath the armholes.

Length is from top to bottom of garment, measured from shoulder to bottom seam, or groin, as applicable to each style.
