I have in the past, but now, as you said, "if you have fun wearing it, do so". That sentiment allows me to overlook some of the different ways of wearing the kilt (i.e. sans sporran or kilt hose, sandals, etc.). Now, should I see a gent wearing it pleats to the front or his sporran slung too low, I may correct that gently, "You know, I've never seen sporran tracks like that before today..."
