I can't wait for someone to answer this! I really don't understand how to find the best formula for bust measurements either!
I'm making a sweater for my mother and I need an answer also. She is 37 inches around by the tape measure.
I know that you are not suppose to use the bra "band" size. I think even though it is a wrap around that you are making, it is still very important to have the right size!
Anyone out there with an answer????
