Collar - Place a tape measure around your neck. At the front of your neck allow two fingers to slip easily between your throat and the tape measure. This should allow for a comfortable fit. But this is a guide so allow for personal preference.
Sleeve length - First bring your elbow up to the same height as your shoulder. Now bend your elbow so that your upper and forearm is at an angle of approximately ninety degrees. You should be measured from the middle of the back (point A), along the back of the arm and around the elbow towards the wrist (point B). Choose where you would like your cuff to rest on your wrist and read the measurement at that point.
