Because of the fox on the avatar, I only think about the forest's smell.
For me, the perfume Lalique Encre Noire is associated with the forest. It is a woody, earthy and musky type of scent. It's a pretty light perfume, and I really like it. I just bought a sample bottle of perfume to see if I would like it or not, but I immediately fell in love with this scent. Unfortunately, I ran out of almost the bottle, and I have to buy a few more to reserve them, haha.
Maybe I should try something new, do you have any recommendations?
