Children’s sizes are based on the child’s age, but as there can be variations in sizes, it is a good idea to measure your child’s height first.
All measurements in the table are body measurements, not actual garment measurements. Measure circumferences using a tape measure, as follows: chest size where the chest is largest (A), waist size at the narrowest part (B) and hip size where the hips are broadest (C). The measuring tape should sit firmly around the body, but not too tight. Arm length is measured from the shoulder to the wrist (D).
