@Marina – That’s a great suggestion! Lots of people aren’t exposed to these art forms at all during their youth. If people start going to such events at a young age, it may seem more natural for people to go. Once, with a high school French class, I went to see the opera. Prior to that, I had no desire to go whatsoever, and never considered it as a possibility.
So, I agree that lack of exposure and ticket prices are a barrier for many people. The reason I bring up the dress code issue is because I personally find it a hassle. Are there others out there like me? Don’t get me wrong, I like getting dolled up as much as the next girl. But some days I just can’t put in the effort (and some days, it takes quite a bit of effort).
