I've seen it done in person, and depending on the tartan, it can look very natty...horses for courses, really. What might not look good to one looks pure dead brilliant to another.

Of course, the waistcoat should ideally be made at the same time and from the same fabric as the kilt, so the tartans "match" as much as possible. The problem with tartan ties are that many times, the tartan of tie does not match the tartan of the kilt.
