So my mother thinks that my wedding should be black tie optional. I'm not opposed to it, as I'm hosting a formal affair that would meet the criteria, but I'm afraid of rubbing my guests the wrong way. With the exception of a select few, I can't think of many guests that would show up under dressed regardless of whether the invitation mentioned black tie or not. I'm usually pretty good with wedding etiquette, but in this case I'm at a bit of a loss. Am I over thinking this? Any thoughts?
