Serge Lutens, well, one option is that you can go to Paris and have your initials hand engraved on the bottle!
If Paris isn't quite possible just now, Harvey Nichols, Harrods, or Net a Porter if you prefer online. But then you can't test.
After I posted earlier I thought about one by Andy Tauer, can't recall the exact name, something like L'air du desert de Maroc. I don't know if they still make it. Gorgeous fragrance.
