I am a big fan of lilacs. When I was little, a friend of my sister used to bring us fresh lilacs from the tree in her garden, and they filled my entire living room.
By far, it is the best lilac scent I have ever smelled. And I've smelled a lot!
I can not smell forward..I know that there's a violet accord and a rose one, but honestly I'm absolutely unable to go far appart from the Neroli of the top notes.
