Some are timeless and some are fashion statements.
What matters to me is wearing what I like from each category.
compare the chanels to the current perfumes.
compare the woodsy 80's colognes to now.
is preference of scent a cultural fad, or are they timeless?
does a preference of a different scent in our current era reveal anything about changing gender roles in our society or is it simply trend-following?
In my opinion, most of the fragrances with significant imp[act on both high culture and popular culture, are simultaneously style icons which pretty much survived the test of time (e.g. as stylish and trendy today, as the were by the time of their release 100+ years ago)
Good points already made.
More than the perfume itself, the advertising sometimes reflects changing expectations and gender roles. Eg the ad for Charlie with a woman in trousers or the like. Or Tabac Blond as the woman who smoked.
A combination of both IMO.
