A: Chest

Wrap the tape around the fullest part of your chest or bust, including your shoulder blades, ensuring the tape measure is level all the way round. Then drop your arms to your sides to measure.

B: Neck

Measure around the middle of neck (at the Adam's apple). Allow room for your index finger to fit between the tape and your neck for a comfortable fit.

C: Sleeve Length

Measure from the middle point of the back of your neck to where your shoulder meets your arm (C1). Then measure from the point of the shoulder to just below your wrist bone(C2). Add these two measurements together, then round up to the next whole number to find your sleeve length.
