As I've said I live in a small Michigan city that doesn't have lots of galas or public functions. But I wear my tux several times a year. The local Orchestra has five concerts a year and I go to two or three of them and I wear a tux. Sometimes someone does ask if I'm in the orchestra, which is interesting because the orchestra is all wearing tails, but that doesn't bother me. The only way to keep black tie as an evening option is for people to wear it. It seems young people want to dress up more. That is why they are wearing suits to work more than their fathers did. If they see people wearing black tie they will see how elegant it is.
