Since I began wearing fragrances in the late 1960's, I 've mostly gone through long periods wearing signature scents. But I kept changing every few years when new ones came out. For a few periods of time, I bought all the ones I liked and alternated.
The one that came coming back as my signature scent was Old Spice.
After finding Basenotes, I entered into another period of alternating. There is no way, after reading about all the scents here, that I can stick with just one. Canoe was my last signature scent earlier this year.
At this time, if I had to choose a signature scent, it would be Bulgari Pour Homme Extreme (with Bulgari Pour Homme bath products).
