Gosh, that's a tricky one you've posed there m8 ; fragrances are such a subjective thing aren't they. I'm very tempted to say original Brut cologne, until I realised that that's just because I shave with Brut soap, wash with Brut soap & splash it on if not quite all over, certainly in a few interesting places. I always liked the kinda clean, understated scent of JF by Floris, which I was given a pressie of one time, however perhaps a more Autumnal one would be Elite also by Floris. This is described by them as "Green woody for men". Unfortunately the only Floris I have (I rely on being given presents of their products as they are out of my price range) is No 89. I'll gladly send you a sample of it if you want, however I wouldn't think of it as autumnal, more as just classic, like a kinda sweet vanilla.
Sorry I can't help anymore, however I'll be watching this thread with gr8 interest to see who suggests what. Plse let us all know what you eventually decide on.
