• For length - Measure from neck to hem
• For chest - Measure from underarm to underarm and multiply by 2 to get the whole upper body measurement.

The length measurement would be the size that you should select. However, some children have a slightly bigger upper body, so double check the chest measurement to make sure it fits. Compare the chest measurement with the chart given. Based on the chest measurement, you might want to go size up even though the length might be a little bit too long.

For a good fit, the child's chest measurement should be about 2 inches less than the measurement given on the chart.
