Panache posted a couple of great photos in the General Kilt Talk section titled New Traditionalists. He is wearing a smooth leather blazer and no necktie. no flashes on his rag-knit hose, and a slightly fashion-forward purple shirt. His shoes are regular oxfords and his sporran is a brown Nightstalker, I believe.

Following his lead, several people have posted pictures that are more and less traditional.

My question are these:

How far can one stray and still be traditional?

What elements absolutely MUST be present in a traditional kilt outfit- let's go ahead and say a traditional DAY kilt outfit?

As a garment and not a museum costume, does the kilt evolve within tradition (thus separating "traditional" from "historical",) or is it fixed?

I went to a meeting last night in a Black Watch kilt, with rag socks, coincidentally, but I was wearing red flashes and "dirty bucks". I had on a striped shirt, but it was under a crewneck sweater and a down vest. I will admit, the vest was also BW patterned, but it was in that thin nylon they make down vests out of, not tartan. I thought of my outfit as casual, but traditional. Was I wrong?

Does traditional daywear imply a necktie?
