I plan to attend a performance of the Hungarian State Opera when I am in Budapest in a couple weeks.
I travel light and do not plan to bring a suit coat to Budapest and my other destinations, but I want to look presentable for my attendance at the opera. I will buy a ticket for a balcony seat or a seat somewhere in the back. If I wore a nice sweater and slacks or a collared shirt with tie and slacks, would one of those be satisfactory? I regularly go to the symphony in Chicago, where I live, and have seen a wide gamut: some people are decked out in fine, expensive attire, others are in mid-range clothes and still others wear blue jeans. I imagine slacks would be OK for my visit to the opera in Budapest.
Thank you.
