Well, firstly I would have waited to book the surgery until I'd at least had the consultation but I dunno, maybe others have done the same as you, just my personal opinion
I'd make sure you've got all your info in advance to be honest as there's a lot of stuff you need to stop doing two weeks in advance of surgery, which is prior to your consultation date, and I think you should have even stopped drinking by the time you go see Mr L
As for the rest, just make sure you understand what you will be about to have done, and explain to him what you hope to get out of it apperance wise to make sure all is realistic
The main thing is that he needs to confirm you def have gyne and talk you through the procedure. The rest is down to any concerns you might have about what to expect before and after the op
May as well get your arnica in now as you'll had to have started taking that ebfore you go as well. I was also advised to take vit C
You don't wear your compression vest until a week post-op but no harm in getting it now....that size sounds like a large but Mr L should send you form for Manufacturers so best checking with them
