Children's sizes are based on the child's age but as there are variations in size, 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 - Measure at the largest point
• Waist - Measure at the narrowest point
• Hip - Measure at the widest point
• Sleeve Length - Measure from the shoulder to the wrist

The measuring tape should sit firmly around the body but not too tightly.
