I've meant to find this stuff. I hope a local store has it. Forgive me for posting and not being able to answer, but I'm reminded to sniff this stuff out. The house's Iris Nobile was good but had the problem of there being better irises out there. With a magnolia scent there might not be as much of that competition problem.
It would be too easy to give you the "if you like it, wear it" direction, Irrbloss, so I'm sorry, you surely already know that. If a store I know has it I'll be able to give you a more thoughtful answer later.
