Breast development

By age 20, most women have completed breast maturation and development.  In rare instances, the breasts may develop later in adulthood.  Breast size does change with weight fluctuations.

20 and "B" cup

While the breasts will change over time, the volume you have now is probably what you will have unless you gain weight.

Breast size throughout life can be variable.

The most likely reason for you to gain significant breast volume would be substantial weight gain. Hormones can certainly change the volume of the breast as with pregnancy. What specifically is going to happen to you is unpredictable.

Will breasts change naturally after age 20?

By age 20, your breasts have pretty much reached their adult size and are unlikely to grow much larger naturally.  At this point, weight loss/gain, pregnancy, etc. are most likely to affect the size of your breasts.

Breast development

At 20's most women breasts are already fully developed . So , unless you gain weight or get pregnant there are very low chances of them getting bigger .
