For jerseys and tops, the chest is the most crucial measurement followed by the natural waist.

C: Chest Circumference - With your arms relaxed at your sides, measure around the fullest part of your chest.
W: Natural Waist - Measure just below the bottom of your rib cage, around the soft part of your waist where your torso can bend freely.
A: Arm Length - Measure from centre back of neck, across shoulder, over the elbow, and down to wrist bone.
