Please let me resurrect this wonderful thread. I'm a newbie and have so enjoyed reading it.
I love perfume, wear it every day. First one I remember having was Floris Stephanotis, a gift from a very dear friend of my mother when I was in my early teens. Loved it then, doubt I would now.
My absolute favourite as a couple of others have mentioned, is Givenchy III which I've worn since the mid 1970s. Givenchy should be made to take a long walk off a short plank for discontinuing it!
Other favourites are Yves St Laurent Y and Diorella and sometimes Cristalle, Lime Basil and Mandarin and Clarins Eau Ressourcante.
Has anyone read Perfumes A-Z by Luca Turin and Tania Sanchez? It came out about ten years ago but is still in print. It covers perfumes from Jicky and Mitsouko onwards, with informed comment about each. What I find so good is that it also gives the "perfume family" for each. Givenchy III is a green chypre which means I can look for other chypres or greens and see if I like them - not infallible, I may still not like them or might love them but balk at the price.
It does reduce no end that "rabbit in headlights" experience in the perfume hall or duty free.
There's a new version covering the years from that book to date. And no, I don't work for them or know them, just thought others might be interested.
