I’ve trawled the internet in search of the most comprehensive list of House Guerlain’s fragrances and I’ve found the most comprehensive to be:
Wikipedia’s article on Guerlain
Basenotes database on Guerlain
and
Fragrantica’s list of Guerlain fragrances
What I plan to do with this list is a surprise! If anyone has any other databases or sources for Guerlain’s fragrances please let me know. 😀
