Before I started NBE I never paid that much attention to breasts, it made simply not much sense to think a lot about it. After I found out that it is possible to change the size I became pretty obsessed with it and also learned more about it.

Anyway, before NBE I thought I was an A and wore B and then I found out I was an AA. I could wear bigger bras, with padded ones it is very easy to fill them, but the actual size is another thing. I also see many girls make mistakes about their sizes, in order to call yourself an A you need at least 13cm=5'' difference between the bust and the underbust. If they are completely full, than it is possible that you fill a bra with less circumference, but most commonly they are not full, you do have a gap. After reaching an A, the difference between the cup sizes is not that big, but to reach an A is a long way. MOst of girls call themselves an A even with 5-10cm difference between the bust and under bust, but actually an A starts with much more tissue. Please see the table.


With a different system, adding 4'' if your band size measurement is an even nuber and 5'' if its an odd nuber and substracting from the bust size, you get the same result.
0''-no difference is an AA
1'' difference is an A,
2'' is a B...
In the charts they say <1 is AA and less. Many girls get the result -2'' or even -3'' and I don't think there is such a thing as AAAAA.

Oh no if you the add 4 or5 inches will give most people an incorrect sized bra with a baggy band and too small cups so no you were most likely an a or b as you thought originally.
You probably don't realise your bras with the add 4-5 inch method don't fit because being small you breast are less likely to bonce or weigh the loose band out of place but for me I have a 30in underbust and 43-44 in bust and if I wear a 34f/g it offers no support at all even though the cups are the right size if I pull the band tight because the 34 inch band is so big it will move all day with moving my arms and bouncing down stairs 30 is my best fitting band size in most bras but 32 is easier to find in gg cup its funny because I really don't have a small build and I see women much smaller than me thinking they are 34 band their bras must do nothing for them.
As for adding 5 inches to get an a cup no the general rule is less than an inch from your true under bust measurement is AAA one inch aa two inches a cup BUT really inches to cup size is only a guideline these days its common for bra fitters(in the UK best place I have found for bras) to measure only the under bust to find band size the find cup size from trying different bras also its important to remember your size will be different in each brand as all styles and brands are different.
For me to buy a bra unless I'm familiar with the brand its very important to try on anything that's not great fit can do more harm than going braless.
