Black Tie means a bow tie not a black coloured tie

[Bugbear]

The balance of the Force has been altered, and we have a bit of wobble as we adjust; it's been going on for a couple of weeks now.

I like to understand the reasons things are traditional or propper rather than just memorizing these things; though I often end up making an idiot of my self before I understand. Sometimes the reason does come down to "it's that way because that is what everyone is used to seeing," and it's not the right time and place to rock the boat.
