Well let me do some explaination, the letters A, B, C, D.... is only the differences between the underbust and the bust (i.e. the differences between like nipples and under boobs) They are the Cup Size
and the no. e.g. 30, 32, 34, 36, 38.... are the band size.
In this Chart it shows how the volume of different cup size are equivlant ie. 32D = 38A Volume wise, they both belong to the 480cc category.
And sometimes the bra changes everything: 
Wouldn't have guess that they are both D+ cups right?
Coz they dont have the 'cleavage'? hence this kinda shows that its not really the size, but more likely is the bra that is making that eye candy cleavage, bigger boobs are not born with that cleavage (its just easier to have that cleavage when u have bigger boobs and wear a push up)
Lastly, here what different cup size looks like (given that they have similar band)
The point I'm trying to make here....
Is that what the media often portarys as the most idea pair (D cups) may not be as seen as voluminous in different body, with different body height, weight it appears to be different, (ie a girl of 5'5 with Ds may look way curvy then 5'7 with Ds).....
So it would be funny to say a certain Cup is the sexiest
What Girls & Guys Said
9 1528d? Does anyone actually wear a bra size that is 28d?
That's my size
Wow, I have never even heard of that size before.
This sounds like complete BS. I'm a 36DD. My boobs are huge & have lots of volume. I couldn't wear a C cup. My boobs overflow. The band 33,36,38 makes sense but cup size, no.
34****
i don't mean u could wear another bra seriously... Coz your band size is totally different what i really mean is that the volume is the same...
