I have tried several sport bras over the past few months.  I wear a 34DD bra, and I thought this would finally be the one that fit.  It is a very full coverage bra, comes up very high in the front, which would have been fine if it had fit.  All it really did was smash me a lot and cut under the arms.  Not a comfy bra at all.  I returned it.  The bra I finally found that worked for me and was really comfortable was the Champion Double Dry Underwire one, so you might try that.
