Hi everyone! I'm so happy to have found this group!
I bought the majority of my collection for myself at the fragrance counter of whatever department store I was in. I replaced most of them as soon as I finished them, but many are original bottles that have been in my collection for 15, 20 or even 30 years. I still have my first bottle of "grown-up" perfume, Caron's Infini, which I received when I was twelve...but I've been through several bottles of the edp through the years (and I keep several vintage bottles on hand so I'll never have to suffer the new stuff.)
Another significant portion came from my grandmothers after they died. They had very different ideas of how they wanted to smell, btw. From one I received Arpege, Madame Rochas, L'air du Temps and Je Reviens, among others. From the other came Opium, Poison, Jardins de Bagatelle and a gigantic bottle of Ysatis. I'm happy to smell like either of them, and they always seemed pretty old to me.
