Just a few random thoughts on solid perfumes.
Like others in this thread, I've loved solid perfumes since my childhood and Avon.
I still love honeysuckle perfume (of any kind) because of a honeysuckle solid perfume by Avon from long ago. I also recall one that was a yummy peach, and came in a container that looked like a peach basket (which I kept even when the perfume was gone, and used in my Barbie house).
My grandmother had a tiny little pot of solid perfume she kept in a dresser drawer. I used to get it out and have a smell of it, though I never wore it. It seemed very heady and exotic to me. I think now it was probably Miss Dior parfum, probably acquired in the late ninteen fifties (I was sneaking sniffs of it in the late nineteen sixties, so it wasn't really "vintage" then
If you want to try out some nice but very affordable solids, have a look at the Lush range. I LOVE the "American Cream", which is a gorgeous vanilla and clary sage. They have others, too, with various citrus and floral scents.
Mandy Aftel of Aftelier makes a number of solid perfumes, as well, but they're pretty pricey (mind you, they do come in a sterling silver compact!).
I like the intimacy and sensuality of a solid perfume. The sillage isn't great, but as I get older, I find I'm more interested in pleasing myself than in whether other people can smell me from across the room
So long as I can smell it and enjoy it, I'm happy with that.
Another nice thing about solid perfumes is you can wear them when you're going to be in close quarters (a theatre, for example, or a plane), and you can get away with them in a "no perfume" workplace because they are pleasantly subtle.
