For me it is about personal style but with careful consideration for the event. When I am at a club listening to one my favorite bands (shameless plug "Barleyjuice") am not about to sit around in my ghille brogues and Prince Charlie, so its the casual kilt and my Docs/Sketchers but if its a more formal event well then the ghilles come out and the Docs stay in the closet. Once in a while I like to mix in my tartan tanks in my casual look but never the other way round. My only pet peeve is when people don't dress for the event, i.e. I was at a Burns dinner and someone showed up wearing a great kilt and ren faire gear. So I say be yourself and wear what you like as long as it is appropriate for the event.
