School Shirt & Blouse Size Guide

Junior shirts go by age; older pupils' shirts go by collar size in inches — measure around the neck.

Younger pupils' shirts and blouses are sold by age; for older pupils, shirts move to collar size in inches. To find a collar size, measure around the base of the neck and add about half an inch for comfort.
