Question:
I just acquired a bottle of Aramis Havana. This is *the* juice. But that's a topic for another thread. As an attempt to match it, I reflected quietly last night and then went with Opium p/h with Mugler's B*Men. I'm not sure if it's close, but it is wide and deep. I like it.
So I ask my fellow Basenoters -- what layers have you tried and found to work well enough to use occasionally (or regularly!), or that do a fair job of matching more complex / rare / extinct fragrance?

Answer:
Gucci PH and Escada PH are sublime together in a 2:3 proportion (more of the Escada)
B*Men and the newer Dunhill for men go together surprisingly well, though I've never tried that combo in public. They both seem to be missing something alone, in my opinion.
Boss Bottled and Azzaro Visit complement each other well.

Answer:
one recent "layering" I like is Vetivyr Oriental with La Myrrhe. Only I never really layer, I spray things side by side with some overlap cause I find whatever goes on 2nd masks whatever went on first. in fact with these ttwo I just sprayed VO on the outside of my arms and LM on the inside and both on my chest

Answer:
Dior Homme and Quorum go very well together in about a 2:1 ratio, with Quorum going on first with two sprays...waiting a bit for it to dry, and then landing a shot of DH right dead center in the chest.
I have worn this before and it is quite nice. The trick is to let the Quorum rest for a bit. (And take a shower beforehand...you do NOT want to rock some Q without bathing.)

Answer:
Passage d'Enfer over Tam Dao, a friend's recommendation. Tam Dao's sandalwood (and other woods) base provides a dark mysterious bedfellow for Passage d'Enfer's frankincense and myrrh. Tam Dao acts almost like an incense booster for Passage d'Enfer.
