Lurking the etiquette board, I have found that the majority would consider the area I come from tacky when it comes to weddings. In reality, it's just the culture of the people around here.I was surprised when the etiquette board thought that bridal dance were some new-fangled way to get people to give you money on your wedding day. It's an old Polish thing. My cousin had one and I didn't think anything of it. If staying true to family tradition is tacky then I guess I choose tacky.
But It really does depend on your culture and circles, which is where you get the social norms.. I was always taught that etiquette is the behaviors that are acceptable within a society or social class, so if dollar dances are the norm in your “society” who is to say that it is poor etiquette to have one? IMO the only thing black and white about wedding etiquette is making your guests feel comfortable, which you should. One of profs in college was all about society norms through history so we had to read a lot of old etiquette books; I sold all the books, but I wish I would have saved them.
