Hey Courtney I had my op with Mr Marcellino last Wednesday. I was also a bit worried as a size had not been decided on and he had also written 400cc and 450cc on my notes. On the day, I found out that he had ordered both sizes of implants so on the day of your op you will deffo have the opportunity to let him know that you want the bigger size.
Hope this helps and all the best for tomorrow
