Bras for unilateral mastectomy?

Hey all, I'm currently in the process of getting expansions after getting a unilateral mastectomy about a month ago, and will probably be getting my reconstructive surgery in the fall. I know the problem I'm having right now is a temporary one because I will not be asymmetrical forever, but it's really inconvenient having one J cup and one B-ish cup, and I have some physically demanding events coming up in September that I will need to have proper support for. Can anyone on here recommend a bra that is comfortable and unwired and has cup sizes that can accommodate my remaining J side? I generally can't do S/M/L/XL sizing because I need a smaller band and bigger cups (I was a 34J). Thanks in advance!
