I know how you feel. I don't think my size difference is as much though. But I have found I go with the size that suits the larger breast (also a dd/e) and then shorten the strap on the other side which is more a d. That helps.. But I have found the triumph "active mummy" i think its called, sports bra to be good. I got them in Kmart & have not seen them since so I am glad I bought 3 of them but I do need to replace them. But they have a good semi crop top style cup that provides good coverage for my forever escaping larger breast.
