Hey!
Big titty girly here, same exact cup size.
While I don't know if this will work for you or if it's a good thing to recommend, this is what works for me.
I use a c cup sports bra, I just couldn't deal with wired bras anymore but, the tightness holds them up great.
Other than that maybe a tight strapless or just a normal strapless, no wires?
Ag......
