...Off topic (sort of) but I have a few ylang ylang perfumes and they smell banana-ish to my nose. "Fleurs des Caraïbes | Comptoir Sud Pacifique" is a banana-like tropical scent, akin to banana flavored Now and Later chews. I wonder if that's what's giving "Songes (Eau de Toilette) | Goutal" its banana impression?
...PowpowOutremer vanille (cotton candy, brown sugar, like vanilla)and even less expensivePacifica Island Vanilla (Tahitian vanilla, tea, bourbon, ice cream)I was going to suggest "Island Vanilla (Perfume) | Pacifica" also. It's my summer go-to vanilla. If you don't mind oils try "Vanilla Bean | Kuumba Made". It's a straightforward vanilla but it's cheap, fantastic smelling, and long lasting.
...Have you tried perfume oils? I really like Alkemia ("Vanille Patchouli | Alkemia" is my favorite), TerraNova ("China Rain | Terranova" is a classic), and Al Rehab ("Dalal (Perfume Oil) | Al Rehab"). Also, I like to use a thin layer of petroleum jelly where I'm about to spray a weaker scent. If gives the scent something to which to stick.
...I'm in love with Kyse Perfumes and Ganache Parfums, both out of Northern California. If gourmands appeal to you, these houses are a great source. The prices are reasonable and the scents are unforgettable. If anything, "Sucré et Fleurs / Sucre et Fleurs | Kyse Perfumes / Perfumes by Terri" was my signature several years ago. I was hooked!
..."Angélique Noire | Guerlain" is my one (of many) true love(s), but there are so many others out there."Vanille Débauche / Vanille Debauche | Kyse Perfumes / Perfumes by Terri" is almost leathery and dark."Eau Duelle (Eau de Parfum) | Diptyque" is fantastically rich yet unsweetened."Black Flower Mexican Vanilla | Dame Perfumery Scottsdale" is spicy and spiked eggnog.Others:"Vanilla Flash | Tauerville", "Vanille Exquise | Goutal", "Vanillary (Perfume) | Lush / Cosmetics To Go", "Spiritueuse Double Vanille | Guerlain"
