How we ranked them
Four criteria shaped the list. Influence first: N°5, Shalimar and Angel each set the model for a whole family. Composition next, judged on the clarity of the idea rather than the length of the notes list. Versatility, because a perfume you can only wear on winter nights does less for you. And presence on skin, rated 1 to 5 in our database. Strength alone doesn't win. Opium and Angel both score 5 and neither is first. Mitsouko only scores 3, yet its structure is still the model chypre. We ignored price and sales figures. La Vie Est Belle is effective but too common and too sweet for our taste, so it stays outside the top 10.
Classics and moderns
Four perfumes here are more than fifty years old, and that isn't nostalgia. N°5, Shalimar and Mitsouko still wear well if you accept a more structured style than today's fruity scents. Expect soapy aldehydes, smoky vanilla or oakmoss. Opium (1977) and N°19 (1971) are a study in opposites. One is spicy and warm, the other green and cool. The modern picks are easier to approach. J'adore is a bright pear and jasmine floral that offends nobody at work. Coco Mademoiselle bets on clean patchouli, Hypnotic Poison on coconut vanilla. Angel stands apart as the founding gourmand, all caramel and patchouli. Libre closes the list with a lavender and orange blossom contrast few expected in a women's scent.
Which one for which moment
For a first serious perfume, go with J'adore or Coco Mademoiselle. They're polished and hard to get wrong. At the office, N°19 is our favorite, its green iris staying crisp all morning. For evenings, Shalimar and Hypnotic Poison handle vanilla in two ways: the first formal and smoky, the second creamy. In deep winter, Opium and Angel need a single spray: their strength fills a closed room fast. In spring, Mitsouko and Libre both shine. Mitsouko warms slowly on skin, while Libre moves easily from day to night. Always test on skin rather than a paper strip. Chypres like Mitsouko change a lot after an hour, and the first sniff tells you very little.
