I recently was hired to do photography at a dinner for a local community nonprofit organization. I live in a small city in Michigan, so far from traditional formal society. My boss told me the event was black tie. I didn't see an invitation so I don't know if it specified Black Tie or Black Tie Optional or whatever. I jumped at the chance to wear my tux while working the event. There were quite a few men in some form of black tie, the rest in nice dark suits. I'm not going to quibble about the incorrect details on most of the men in black tie. I was just happy to see so many men make an attempt to fit the spirit of the event in the middle of Michigan.
