Bra sizes--am I the only one who didn't know this?

According to the chart posted,I'm a 32 DD.
Why my boobs seems to grow bigger,instead of shrink,when I loose weight?Sigh.

Mine are not very full but are kind of spread out, if that makes any sense. For some reason I have always thought I was a 36 A or B. Then my daughter actually taught me the correct way to measure and it turns out I'm a 34D in a demi cup. Go figure.
