Hi Plaisir. It's been a few years since I owned any Aftelier, but I found that they had pretty good longevity. Those I used were definitely not light...some I'd describe as pretty hearty. Most of the ones I once wore no longer appear on her website. I did try Tango and remember really liking it. Her website says that her perfumes typically last 2 hours on your skin but I remember some that lasted a good 8 hours on mine. As for house note/accord...I remember her perfumes smelling dramatically different from one another, unlike Strange Invisible Perfumes, for instance, which I sometimes have trouble telling apart. I've heard wonderful things about Secret Garden!
Hope someone with more recent experience can be more helpful.
