I just sampled Lubin Idole and really enjoy it especially the classy feel it has... What niche fragrance would you say is even classier? Also do you feel Idole has disappointing longevity?
Not sure which version you mean, but the EDP has very good longevity. Don't remember about the EDT offhand, have only worn that once so far.
I think Creed Spice & Wood, Creed Millesime 1849, and Ormonde Jayne Ormonde Man are very classy fragrances also.
I have Idole EDT, and longevity is what I would consider "good", but not "great". 6-8 hours in a workplace wearing, on average. Having smelled the EDP, I kind of wish I'd picked it instead, but not necessarily for the wear time, I think it's a tad bit smoother.
I love Idole de Lubin and get longevity on the low side of average.
Some fragrances I particularly think of as "classy" are:
Dia Man by Amouage
Richard James EdT by Richard James
Tiffany for Men by Tiffany
Bentley for Men Intense by Bentley
Monsieur de Givenchy by Givenchy
Probably of these based on your enjoyment of Idole, the Bentley for Men Intense may be a good place to begin exploring...
