I personally stay away from anything with underwire -it just gets uncomfortable.
Nursing bras may also be really good support
I wear sports bras and they are so comfortable.
I LOVE genie bra, personally. Im blessed by the boobie fairy and the genie bra works for me. Im in love with it. A combo of sports bra and supported wire bra but no wire. And its soft. Lol. I have an apparent unrequited love affair for genie bras now haha
Im glad your thinking straight I purchased bras from B to DD from Vs just cuz I was so happy to finally have boobs lol up to now thats all I still own but regret spending so much
