I have only one tailored kilt, by Howie Nichlesby (sp?). I don't know if I got the special speech for foreigners, but I was told quite clearly never to let the kilt hang lower than the top of the knee for formal wear. But then I was also told that slightly lower is fine for casual wear, and the camo kilt he was wearing himself that day was covering his knees quite thoroughly.

I suppose fashion changes even for kilts!
