a full body measurement size article you can read here

Using a flexible tailors tape measure, wrap it around the breast to get the bust size measurements, then use the tape measure to get the length below the breast which is called the band measurement or band size. 

          Bust Size minus Band Size = Cup Standard Size 

          Band Size add Cup Size = Bra Standard Size

If you have a larger bust size and a smaller band size you will get a larger cup size. 

For bust measurement and band size measurement using a tape measure, it is always important to consider the gap between the chest or from breast to breast to avoid loose measurement.
