Neck: Measure around the base of your neck.
Chest: Measure around the largest part of your chest, keeping the tape snug but loose enough that you can comfortably take a deep breath.
Waist: Measure around your natural waistline (where your body creases when you bend to the side), keeping the tape snug but loose enough that you can comfortably take a deep breath.
Hip: Measure around the largest part of your hips.
Arm Length: Put your hand on your hip so that your arm is angled. Measure from the center back of your neck to the tip of your shoulder, then continue to your elbow and down to your wrist. You may want a friend's help!
