To check sizing, measure your child around each of the areas indicated. Body measurements are most accurate when your child is standing up, with arms down and shoulders relaxed.
Measure under your child’s armpits, passing the tape across the fullest part of the chest and around the shoulder blades.
Measure around the body just above your child’s hip bone, around the natural waistline.
Measure from your child’s crotch to the bottom of her heel.
