To measure your child you will need soft measuring tape and your child of course!
Chest: Align the measuring tape to your child’s arm pit and measure around their back and across their chest, keeping the tape level and straight.
Waist: Start right above your child’s belly button and measure around child’s back and waist.
Hip: Measure around your child’s hip, which should include their bottom.
Length: For dresses measure from the armpit to the length given in the size chart to determine the length the dress will be on your child.
Inseam: Measure from the crotch down to the number of inches given in the size chart.
