step by step measuring guide    
  #15 side to nipple
The following breast measurements are of great importance. Please measure correctly and make sure the breasts are always in the same place. If you like your breasts to be lifted, make sure that you have them in a position that you like at this time. This can be done by wearing your favorite bra.
   
  Start measuring on the half side of the body (at the height of the nipple) to the nipple itself.
