Lately I've become obsessed with vintage fragrances, mostly because I'm in the process of recreating the mid-1930s in my tiny St. Louis bungalow. So I've been wearing the kinds of scents that a woman would have worn if she'd lived in this house about 75-80 years ago: Emeraude, L'Aimant, Tabu, Crepe de Chine, and L'Origan. I look for original (vintage) bottles on ebay, because the modern reformulations have very little resemblance to their lush, beautiful ancestors. That's true of the high-end fragrances as well, from what I've heard.
For modern scents, I still love Aromatics Elixir. Actually, my favorite vintage fragrance is Youth Dew, but it's a little too modern (I think it was launched in 1953) for my house -- not that that matters.
