The White Bow-Tie

[ItsLouis]

Hello all, I posted this in another thread thinking it didn't deserve it's own but having remained unresolved I thought I'd put it here after all.
Hopefully you all have opinions on the issue or else can direct me somewhere where they might.

The subject: The white bow tie in white-tie attire.
The source of interest: Titanic (1997)

So I'm aware that movies are often far from accurate and are rather interpretive in their sense of historical dress but:
In the movie, I'm pretty sure there is a moment at which the bad guy (Billy Zane?) is wearing his wonderful white-tie attire with a pointed, batwing bow-tie of off-white satin.

Not that I plan on doing it any time soon, but how acceptable would this be considered do yo think? by traditionalists, by savile row tailors, etc.
