Nc I guess is a modern classic green herbal frag. Like Polo by Ralph Lauren or Z-14 by Halston. Although NC is not a classic its traditional in that way. Its nice but to some the patchouli base might be to much. BB is a vanilla with a tea note that smell like rubber (literally) So if you like you vanilla with rubber then this is for you. I cant really compare it too anything else because I have not smelled something with a rubber note in it but I get it. I am guessing it work during colder days when the is air is crisp and one wouldn't mind smelling some rubber to balance out the sterile temperature . It just takes you out of your comfort zone I guess. Enjoy.
