Nice your body is already beautifully curvy you might be able to wear 34a bra from your measurements.

That's interesting, how did you work that out? I figured I would need 36-38 band size (I use 38 when crossdressing). I guess the smaller band size would work out because I'm like an AAA or something like that ;-)

You should wear a bandaize as close to your under bust measurement as possible and you have difference in bust an inch or more even if you don't fill it could be a first goal.
Look at these

Here's 34a but probably not completely accurate and padded because its a Victoria secret bra
