Today was our first rehearsal for the opera, a month-long project. After the break, our rehearsal proctor, held up a long-sleeved black shirt and made an announcement. Because of the hot Japanese summers, men would not be required to wear tuxedos for the opera. Instead they could wear all-black. There was a lot of cheering. He went on to say that there may be an exception to this for the last performance: for this, we might wear an opera-logo polo shirt, however, this is yet to be decided. I'm glad I have time to prepare myself.
