This is Guerlain's legendary vanilla, but it's a divisive one. Many find it exquisite, a rich and boozy dream, while others rage about its weak performance and high price. You might love it, or you might find yourself anosmic to its charms entirely. Sample first, and pray your nose isn't broken.

This one's a proper head-turner, but definitely not for everyone. Expect a divisive concoction of churchy incense, grown-up cotton candy, and a hefty amber warmth. You'll either adore its mystical depths or find the sweetness jarring.
