Let it all hang out.
OK, so last year I went to a wine festival. I mention this to point out that it wasn’t a rock concert or something ultra-hip, a place where people dress in the latest hot meatmarket club-culture clothing. One sight that stood out in my memory was an otherwise conservatively dressed, pleasant-looking twentysomething. She was sitting on the ground apparently unaware that her jeans had ridden down and she was displaying about two and a half inches of butt cleavage to the throngs walking past her. At the time, I debated mentioning something to her. But now I read that she might have just been ahead of the fashion curve.
