Use this page as a guide to the sizing of your chosen garments. The age bracket will give you a fair indication as to sizing, but not all companies size the same and not all children of a particular age are the same size! We suggest that, rather than measuring your child, you measure one of their garments which fits well and use the measurements below as a guide.
