Hey guys. I feel weird asking this, but I was just wondering if any one else has run into this issue.
I'm trying to work out a plan to save money for top surgery (Top surgery is a long way off, but I guy can dream.

). How much I need to save obviously depends on who does my surgery, and who does my surgery depends on what surgery I can get.
Most of the surgery guidelines I've seen, as far as whether you can get Peri or DI, have centered around cup size. I have absolutely no idea what size I am, and the internet isn't really helping. Some sites say to add four or five to the under bust measurement, and others say not to. I tried both, and there is a pretty significant difference between the results; enough of a difference that one puts me in range for Peri and the other says I'm nowhere close.
I guess what I'm asking is, does anyone know how the surgeons measure?
Any help would be really appreciated.
