How big they are depends on how big your chest just below your breasts is.
If you want to get the right size bra, get a cloth tape measure and close the door to your room. Take off your top and bra, then take two measurements. The first is around your chest just below your breasts. This is the "band size" and it's the 32 in 32C. Write this down.
Next, measure around your breasts at the level of your nipples. The number of inches larger the second measurement is than the first, is the letter.
1" larger--A cup
2" larger--B cup
3" larger--C cup
4" larger--D cup
5" larger--DD cup
So...if the first measurement is 32 and the second is 35, you are a C cup. Buy a 32C bra and be nice and comfortable.

About a C cup. Though I did hear at one point that the average breast size in the U.K. is a D cup.

Bra Size/ Breast:34 C
The letters indicate the bra's cup size - how big the breast itself is. The number before it is the distance (in inches if you're American) around the girl measured right below the breast. A (or maybe even AA) is for small breasts, and the size of the breast gets progressively larger as the cup size letters progress from A to D. A is very small breast. B is larger than A, but is still a fairly small breast. C is larger than B. D is larger than C and is a larger, but not overly large, breast.
