I regard most of these charts as useless, but the following one works well for me:

can you explain why this chart works for you? it seems very off to me. my under bust measurement is 29 and my overbust measurement is 34.5 and i am NOT a D cup!

Golly, it says I'm a 28F. Not sure if that sounds impressive or not but am sure a 28 band size would cut me in half and choke me to death.

hey fairiecat...maybe we should start modelling for Juggs magazine! somehow i don't see this in my future!

This chart is crackers. I tried it with my sister's measurements who is a very average size with a reasonable bust, I'd describe her as a typical 34B bra size. But according to the chart she's a 32DD !!

I'd call this the wishful thinking chart. The answer is completely whacky but I wish it was true.

Come fricking on! I'm an AA and it says I'm a DD! This isn't even funny.

It says I am a 32D. That's just crazy.

I believe I am a 36A now. That is what the other chart says and the band of the 34A that I bought is getting a little snug, so that sounds about right to me.

It works for me, just a cup size too big. :) (You have to pay attention... the cup sizing is weird because they don't double as many letters as some brands do.)

My under-bust is 27" and I wear a 28.
