Specifically, I'm looking for scents that aren't just pumpkin spice or similar. I like pumpkin quite a bit, but I'm more looking for a general Halloween atmosphere.
I have Foxcroft Fairgrounds on my wishlist to try already, and I think that will fit the bill nicely.
I like Fantome Ectoplasm and Wicked Vanilla Woods, too.
What I really want is a fragrance that smells like Halloween Horror Nights: fog machines and wood. I'm not sure if there's a perfume like that.
