To find the right size school shirt for your child, you will need their collar measurement.

To measure their collar, wrap the tape measure gently around the base of their neck. Put two fingers between the tape measure and their skin while you do this; this will ensure a more comfortable fit. Also check the chest measurement of the garment as well to make sure these two areas both fit. It’s better to have a comfortable, fitted chest and a slightly looser collar than a well-fitted collar and a chest that’s straining at the seams.
