Hi! I've never posted before but was so impressed when reading through the threads about correct bra sizes that I thought perhaps you would be able to help me too. Always hated my boobs as they so small. Flat-chested 
and one larger than the other Was A cup before children and now been wearing AA and wondering if I need AAA as my boobs seem too small for all bras
I read the link to the "Bra guru's better bra campaign" blog that you posted and have got the following measurements:
Underneath: 31 inches (or possibly 32) - it was a bit tricky for me as only got a rubbish paper tape measure with inches so kept re-checking with the proper one which is cm only. (Bit 
as always thought I was a 34 or even 36. Perhaps lost weight recently? Or toned up as exercising more... Actually thought I had put on a couple of kilos).
Bust: 35.5 or 36. Again I have two measurements as have quite protruding nipples so tried to squash them down a bit to get the true boob measurement - not that easy when not much to work with!!!!
For the underneath measurement, i am pretty thin and don't have any padding round my ribs.
Are there any places you recommend particular to buy bras from? Have tried max cleavage online and we also have M&S here (I live overseas).
Huge thank you in advance!!! Am very excited to see what you will tell me!!!
