Ties and kilts

[Lyle1]

It appears generally accepted that a break between kilt and tie is acceptable as with a waistcoat.
Personally, I like the look of a matching tartan bow tie rather than just plain black bow tie when wearing my Prince Charlie jacket & vest.
I like it and I feel comfortable.

I have also worn a matching tartan bow tie (silk) when wearing my kilt with formal wear. I think it works because the sett is much smaller and the there is an expanse of white shirt front and a waistcoat between the tie and the kilt.
