Ask yourself this: If the event was being held in Vienna (or Graz) would it be appropriate for your wife to wear her Drindl?

The whole point is to dress to the level appropriate for the event you are attending. Having said that, I would generally caution against wearing any "national folk costume" to an event that wasn't specifically celebrating that nation's folkloric culture.
