Use Size Charts
STEP 1: VISIT A PRODUCT PAGE
STEP 2: VIEW GARMENT MEASUREMENTS
IMPORTANT NOTE: these are the actual garment measurements (not your child's body measurements). It is important to remember this.
STEP 3: COMPARE TO YOUR CHILD'S BODY MEASUREMENTS
ADDING 1" TO 3" TO YOUR CHILD'S MEASUREMENTS: Remember that your child's measurements are going to be smaller than these garment measurements. We recommend that you add 1 inches to 3 inches to your child's body measurements to ensure a comfortable fit. For example ... if your child's chest measures 26 inches, we recommend adding 1 inches to 3 inches (27 to 29 inches) & using this larger number when comparing sizes using the garment measurements chart. If you prefer the item to be more form fitting, you may want to add only 1 inch to your child's body measurements. If you prefer a looser fit, you may consider adding 2 to 3 inches to your child's body measurements.
