Hi Maisie,
I also had Dr Sleiter like Brigitte, I thought he was fab, can’t fault him at all!
I’m 5ft, 7st and was a 32a. I had 300cc HP textured round over the muscle. I’m now a 32d which is what I told him I wanted to be when I first met him!
If you want a quite natural look they usually tell you to go for a smaller size under the muscle, but of course everyone is different and it certainly depends on how much breast tissue you already have, and the skin surrounding the breast too. I have thin skin so I’m glad I didn’t opt for bigger, I was also at risk of double bubble hence the reason I had to go over the muscle.
I am very happy with my results though.
Best of luck!
