Vienna Philharmonic concert

Vienna is in Austria.

I wore simple dark regular travel clothing and did not feel out of place.

Vienna Philharmonic does a lot of touring (November in Japan and China), so I see a few concerts in Germany. In Vienna, the concerts are mostly subscription, so any tickets are returns from subscribers who can't make it.

There is no dress code. Wear what makes you comfortable. Most people will be wearing business casual. Formal dress would be very out of place.

Thanks for the quick replies. All very helpful!
And yes, Vienna, Austria!
