For me, the only relevant Private lines from the designers are Tom Ford and Dior.
Armani Prive has the be the biggest scam in perfumery. Hugo Boss is mediocre at best, as is Zegna's.
Its generally the designers trying to cash in on the lux category. It leaves a bad taste in my mouth.
All of the sudden everything has to be considered "Niche" to be interesting. How the hell did we get by in the 80's and 90's? Everything must have been niche i guess because it was ALL more interesting.
Don't ever forget its a business!
