Bra cup sizes are a letter that represents the difference between the underbust measurement and the one around the fullest part of the bust. Each cup letter represents an inch of difference between those measurements. For example, a 34B bra means that the band size is 34 inches and the difference between the underbust measurement and the measurement around the fullest part of the bust is 2 inches. The chart below shows the cup size lettering that is generally used:
