If there is a truly genuine, unadulterated lavender scent, it is Lavande Romaine by Perris. My husband and I were both immediately thrilled when we had it sprayed on us at our perfumery. So real, so true, so beautiful. We both enjoy using it very much, and it also layers well with other Perris fragrances like Arancia di Sicilia. Unfortunately, it doesn't last very long, but at the more than fair price, you can easily reapply. Our recommendation for lavender lovers and as a base for other perfumes, definitely give it a try.
I smell it too, exactly like that. I received the fragrance as a bonus with a scent package, and even though lavender isn't really my "type" - since the perfumes rarely capture the herbaceous notes well - I'm really impressed here!
