                                                          Bra cup sizes generally range from A (smallest) to G (largest).  However, some brands refer to E, F, and G as DD, DDD, and DDDD.  Additionally, some brands carry a AA, which is smaller than an A-cup.  You can measure your bust under the breasts and then over the breasts to come up with your correct cup size.
