I am a total perfume slut, but some of the key scents in my life:
School days - Miss Dior was my first proper perfume, but I also had things like Body Shop White Musk and Dewberry.
Year out between school/uni - Anais Anais, Chloe in the peach coloured box, YSL Paris, Jasmine oil from a little Indian boutique place.
Uni - Issey Miyake, Calvin Klein Eternity, CK One, and Obsession, Cabotine, Laura Biagiotti's Venezia, Carolina Herrera in the white box with black polka dots. I had a Saturday job in a shop that was part of the Debenhams group, and pretty much ploughed my wages back to the perfume hall, with the staff discount card.
20s - first job, year out to do Post-Grad, and beyond - Gucci Envy, Chanel Christalle, Chanel 19, Anna Sui in the lilac bottle/box. Got given Chanel no 5 for my 21st and felt guilty that I didn't really like it.
30s to now, early 40s - Chanel 19, Coco Mademoiselle, TF Black Orchid and White Patchouli, VW Boudoir. I started getting into more "niche scents" around this point, and now have small fortune's worth - key players are Miller Harris, Heeley and Frederic Malle.
