Reviews of Hermes Hiris
From boisdejasmin - "Smelling Hiris recently made me poignantly aware how much my scent perceptions have changed since I first smelled it 10 years ago. Then it struck me as a sophisticated and mature fragrance, requiring red lipstick and a manicure to match its lady-like demeanor. Today I still find it elegant, but above all, it conveys to me a lighthearted, effortless elegance, a comfort in one’s own skin. Wearing Hiris, I feel serene and content. While it is an unobtrusive fragrance, it is definitely one that makes others lean in and inquire, “What are you wearing? You smell so good.”"
From nstperfume - "The opening notes are simply stunning: crisp, dry and peppery iris, with lots of dirt-caked roots and greenery. I did not recognize the carrot note until I smelled L'Artisan Fleur de Carotte, and so learned what a carrot translated into perfumery smells like. Yes, there is carrot in Hiris too, although only for a brief while. As it dries down, the high pitched, almost metallic hum of the top notes calms, and the hay and wood notes intensify, along with a tiny whisper of rose."
