Measure your chest at the widest point, and your waist at the narrowest point (when you bend to the side, the crease that forms between your bellybutton and ribcage is your waistline).
Measure over your undergarments only.
When choosing your size, go by your largest measurement and select the size that corresponds to that.
All measurements are in cm
