My experience with these two scents mirror's Aaron's. [Can't say I've ever dated
a supermodel, though.
The original (1955) is my favorite, but it doesn't last as long as the Concentree version.
Concentree has a memorable nutmeg note and a fine drydown. Pour Monsieur (1955)
is quite the lemon-lime on the top notes, and it drys down to a very fine chypre. It's
the epitome of class, and just smells great. Either one will make you better smelling
than the _vast_ majority of other scents will. It's worth owning both if you can find them.
