I havnt had mine done yet, but from consultations with surgeons I have had they decide what size is your max from your frame etc… I am a 32/34 A size 8 5’3 and the largest I have been told is 410 cc unders, that was MYA, so that will give me a large C small D. It depends were you shop I guess. My advice would be to go to lots of consultations, try the impants in the bras and see what looks good. I am not sure about finance hun sorry,
Good luck x x x
