My 4 go-to aftershaves are Creed Aventus, which is unreal, One Million, Jean Paul G and Paul Smith Extreme.
+1 on Creed.
Depends where I'm going/what the occassion is really.
For nights out/special occassions, CREED Green Irish Tweed (expensive as fuck)
For normal days out, its cheaper distant cousin Coolwater by Davidoff.
Also use: Acqua di Gio by Armani and CK be
