Well, I'll sort out what to do with the burgundy bowtie. I can understand that it might be best for the more formal situations. I think it would look good with the double brested, navy blue suit, in what ever formality is just below black tie, to not let it go to waist.

As far as black tie, I was leaning toward the jabot with the Highland attire; I guess a black silk tie wouldn't hurt to have though.
