What Bra size would I be with a 34 inch bust and a 27 inch ribcage?

If I am a 34 around my bust area and a 27 around my ribcage, would I be 32dd or something else? Because I have 32dd bra from VS and it does give me back support, I am just wondering if I am wearing the right size bra. So what bra size would I exactly be?
