...FloraMilena:Well I could make a huge list, but I will only post what works well on my skin of those I have tested. I think these are definitely worthy to be classics:...Chanel - GARDENIA...Here's my insufferable know-it-all moment, this one is old as balls already :) Tho I do agree with others, there are some aspiring classics in the Les Exclusifs line. My personal favourite for that status is ofc "31 rue Cambon".Mugler's "Angel" is a legend in its own right, and it's not exactly new any more either so it's beside the topic, but some of Mugler's other fragrances may also stand the test of time and become classics. "Bvlgari Black" definitely has potential IMHO, and so does/did the now discontinued "Omnia". Those spring to mind and seem to rise above others, anyway. It's really interesting to see what others have suggested!
