I see many comments/questions on the forum regarding appropriate attire at the Hungarian State Opera House in Budapest. My wife and I attended am opera performance there yesterday evening, Aug 14, 2025, so I'll share what I observed.
We had box seats in the middle level, two seats from the King's box.
The temperature when we left for the Opera House was about 96degrees F, which may have affected what people wore. As the humidity was not high, it felt quite comfortable to us. (Also: fortunately our lodging is a very short walk from the Opera, so the heat was not an issue for us.)
Other than the staff, I only saw 3 men with suits and ties -- one of whom was me. To my surprise, the mix of attire was about the same regardless of whether people were seated on the main floor or in boxes. I observed:
- Just 3 men with suit/tie
- Several with blazer and no tie
- Many with just a long-sleeved shirt, mostly in white or a light color, but a few in dark colors
- A lesser amount, but still numerous, in short-sleeved button-up or polo shirts
- a very few in solid color t-shirts - including a gentleman in a box seat
Another surprise was that most of the folks in the box seats appeared to be tourists. Several didn't return after the intermission; for example the 3 boxes to our right were empty after intermission.
