black tie, white tie

[Bugbear]

I look at it this way; though the analogy is not perfect.

It is like being at a very nice theater watching a very good movie. During the movy someone starts playing with a laser pointer up at the screen. That is like a person dressing improperly for a black tie event.

Lets say the person brought a powerful flashlight instead of a laser pointer. That is like showing up in bermuda shorts and hawaiian shirt at a party that is anounced as black tie.
