PLEASE NOTE: This size chart has been provided by the manufacturer. Figures are based on the garment measurements (chest and waist) in inches, not the childs body, so you will want to go up 1-2 inches to allow for easement and comfort. Chest is measured one inch below the underarm. Check drop down menu for sizes offered as sizes offered are by style and not necessarily made in all sizes that are listed above.
