It's been a very odd spring in my little corner of Pennsylvania: first way too cold, then way too hot, and only just recently approaching the happy sort of spring temperatures I look forward to all winter. That's probably made it a little easier to think about which vanilla perfumes might work best for the gamut of spring weather (I've already covered fall and winter). As always, do chime in with your own picks in the comments!
Aedes de Venustas Cierge de Lune: With a creamy powder finish and a hint of warm amber, Cierge de Lune is probably best suited to the cooler days of spring; Angela aptly noted that the sillage is "almost visually golden". It's arguably the most sophisticated of today's five, and it has a price tag to match (although if they ever release it in the travel spray trio, the price is not really that much more than the other niche fragrances listed here).
Annick Goutal Nuit et Confidences: I like the brand's Vanille Exquise better, but Nuit et Confidences is just the right middle-of-the-road weight for a day that might start out in a sweater and end up in a tank top. It's middle-of-the-road in lots of other ways too: not too foody, not too sweet, not too dry, not too youthful, not too mature. It would make a good no-brainer vanilla for almost any time of year.
Atelier Cologne Vanille Insensée: Another candidate for the no-brainer category. Kevin classified Vanille Insensée as a "diet gourmand", and while it has enough citrus to keep things lively on a sunny spring day — and better than usual last power for a diet fragrance — you can also brighten it up in the last afternoon with a spritz of any basic grapefruit or orange. As an added bonus, the 10 ml travel spray is less than $30.
Caron Pour un Homme: The classic vanilla and lavender, bracing but comforting, easily adoptable by any gender. If you're willing to shop at the discounters, you can get 120 ml for about the same price as the travel size of the Atelier listed above. I wish I could tell you it's every bit as good as it used to be, but I haven't smelled a new bottle in some time. Do comment if you know!
Providence Perfume Co Provanilla: A blend of five kinds of vanilla, and appropriately delicious without being so foody as to cross into cupcake territory. Provanilla is a sort-of aquatic, but it's also the only natural included today, and that means no calone (in case that's as much a plus for you as it is for me). You could probably wear it year-round, and I've stuck it in the spring list just because.
