Just an observation that seemed like it belonged here more than anywhere else...I went to see Luisa Miller at La Scala last night, which was lovely, but did not see anyone wearing black tie, orchestra included. I saw one guy wearing a tuxedo jacket and jeans, but that was as close as anyone came. I asked casually whether one might see some dinner jackets if it were a weekend performance, but was told no. Incidentally, despite the absence of semi-formal evening wear, most men were quite well dressed, including a much larger share of black shoes than I would have expected in Italy.
