Question:
I would just wear something that makes you feel confident. She's married, and you haven't seen her for a while (sounds like), so go with something that that's not too sexy. Good luck and have fun.

Answer:
Update-
First, thanks for everyone's suggestions. So far, based on the forecast weather (26c) and the time of day (meeting about 6pm) I'm leaning toward either Gucci Pour Homme or Terre D'Hermes. I know how they project, and they are both great warm weather scents.
I'd probably wear the Chanel Pour Monseiur if it were in my wardrobe already.
Then again, Havana has many votes here and despite being a big scent works well in such muggy spring weather. And I haven't ruled out M7 yet...
I sound indecisive, but I know I'll choose well when the time comes.
Thanks again everyone!

Answer:
well, I might be too late to catch this wave, but since you mentioned VC&A Pour Homme is in the running... well... few scents ooze class like that.
She will wonder which white shoe firm you've been with all these years!
Hope you had a nice time reconnecting.

Answer:
Go with Gucci Pour Homme. It's a confident warm fragrance that will not offend and usually inspires confidence. Terre Hermes is also good for people who feel intellectullay superior - it is so soft but difficult quite difficult to define - and it is new. The best fragrance is the one that comes from within the self - let yours shine!

Answer:
Chanel Pour Monseiur
without question....
