Even though I wouldn't mind wearing it daily, I think some of the classic perfumes will fit your description of classy.
It's really hard to pick just one, but if I have to, it would be the vintage, original "Chloé" by Karl Lagerfeld.
As for a perfume that makes me feel like it's wearing me rather than me wearing it, I would say my bottle of "Shalimar Parfum Initial". It is so powdery that it makes me aware of it at all times, no subtle and smooth there.
