Another May wardrobe crisis

So I'm going to Toronto this weekend for a hearing aid conference, put on by the same people who made me wear something fancy last year. This year, they want us to dress up for a rock concert. And, once again, I am stuck for something to wear.

I'm also wondering if it's worth ditching a reception to see some theater or go shopping. Hmm... food for my belly or food for my soul. Tough choice.
