I could live without any of them but the one I'd think about the most is Patou pour Homme.
Midnight in Paris
Montale's Black Aoud
Caron Pour un Homme
Honorable Mention: GIT
Le Labo Rose 31
And lots of honorable mentions (that I won't mention)!
Guerlain Double Vanille, floors me every time!
Caron Pour un Homme
Dunhill Blend 30
Parfums MDCI - Invasion Barbare. I could start a cult around this fragrance - it's divine! :)
Rive Gauche or Dior Homme. I guess Rive Gauche is more versatile so that.
Yatagan. It holds too many memories and associations to let it go :0)
many many many!!
but especially Chanel pour monsieur concentré.
In terms of hard-line necessity, either Agua Lavanda or one of the Guerlain eaux. Which doesn't much matter, as their merits and disadvantages seem to equal out. I would no sooner try to get by without one of these than I would without soap and water.
However, in the realm of actual fragrances (the aforementioned are more hygiene products), Monsieur de Givenchy is foremost among the fragrances I hope to always have to hand.
