Dress code in the Rudolfinum (Prague)

I have no idea. But here is a photo:

Unfortunately we are not sure either, but I would recommend emailing them direct to get a definitive answer: info@cfmail.cz

Attended a concert in 2010, no dress code.
if there were a code, surely they would show it on their we page as a condition of entry..

I could only find the one photo of guests at the Rudolfinum, but I found this photo from a much lesser theater in a much more primitive and backward Central European country:

Google some photos yourself and make your own decision.

It does make a difference whether you're going to a short "tourist concert" there, or a subscription performance of the resident Philharmonic. There are a zillion tourist concerts in Prague, some of them very nice. In any case, with the passage of time and the Great Recession, there is not the slightest worry that you will find men in top hats and women with fox stoles sipping champagne in the lobby. If you dress neatly, at least as well as you would for a country-club Sunday dinner with a grandparent, you'll be fine anywhere except maybe on New Year's Eve or Easter.

I guess if you contact them directly there are three questions you might be interested in asking.

1. Is there an enforced dress code?
2. What do people generally wear?
3. How would you recommend that I dress?

Again, not from Prague, but from another theater in the same region showing the guests: http://bucketfullofwords.files.wordpress.com/2012/01/dsc_0250.jpg

That is odd - we were just there yesterday for Haydn`s Creation concert - we had booked tickets last minute, so did not have any formal wear. I went with a polo/slacks/sneakers, while SO went with black spats and blouse. No comment from the staff, and we also saw others similarly dressed.
