What percentage of people actually adhere to the dress code (tux/gown)? I am invited to a wedding in a few months, that says "Black Tie" on the invite. Whether it will hit all the black tie requirements is to be seen, but quite a few people have been complaining about attire as this particular crowd does not own tuxes (and in some cases long gowns) and has travel to the wedding. I have heard some things about a fancy cocktail dress being appropriate for these type of events. Did people at these events wear fancy knee length dresses?
