Bogart PH is similar to a degree but has a boozy aspect to it that is missing in B to B but is much better value. I can't actually think of a designer fragrance that comes close, except the obvious T & V from Tom Ford (is Tom niche?). This isn't very helpful is it? I can confirm that B to B is basically a honeyed tobacco.
I really really love B2B, cherry tobacco is the most dominant note in it based on exact ingredients I viewed at the store, it is really warm, a bit of a bad girl scent to me, honey is in there too, it is sexy, very yummy, sort of gourmand in a way, one of my faves but it requires a certain mood. It is a good value in my opinion if you get the travel set refill and do not care about the packaging.
Buy the refill bottles of by Kilian's, the juice is AMAZING, however, the price includes the excellent bottle & packaging, which to me was too much to waste. I own 5-6 from this house, all are excellent, but as I said, I did not buy the invididual bottle with casing etc...Saves u a lot if u buy the refill's and then buy a cheap atomizer for it.
