Yes, they do go out of style. I guess it might be fairer to say that they get associated with a certain generation or demographic.
I’m a GenXer and I used to love Cool Water, Eternity and Nautica. I stopped using the Eternity because something about it bothered my eyes. My best friend used to love wearing Polo.
My old college girlfriend used Estee Lauder’s Pleasures and I absolutely loved it.
I imagine most millenials and zoomers want nothing to do with what either of us used in the 90’s.
All the lower to mid-priced perfumes today smell like fruit or candy - and pretty much all the same.
Taste in just about everything is degenerating rapidly.
