Generally, the A cup is considered the smallest available but for some this is still too big and compensating with a smaller band size won't help.

C cups and D cups differ in circumference by an inch. A C cup has a 3-inch difference between the bust and band size while a D cup has a 4-inch difference. C cups will weigh a few pounds less than D cups. Both of these cup sizes can look bigger on a petite woman and smaller on a full-figured woman.
Contrary to popular belief, a C cup is not a large size. It is the most common size among women who have breast augmentation or breast implants.

When does breast development begin and end? In general, breast development begins between the ages of 8 and 13. A girl's breasts are typically fully developed by age 17 or 18, however in some cases they can continue to grow into her early twenties.
Breast development in girls is considered delayed when breasts don't develop by age 13. The commonest cause of the delay is that it runs in families. Another common cause of delayed puberty in girls is lack of body fat. Being too thin can disrupt the normal process of puberty.
