How to Measure

Torso:

Ask a friend to run a tape measure from the top of your shoulders (i.e the same place where the collar on a crew neck T shirt finishes), down your back to your waistline (ie the small of your back, at the same height as your naval or the top of your hip bone).

Waist:

Run a soft tape measure around the narrowest part of your waist, just above your hip bone and in line with your naval.
