Hmmm... I do find that I use a cubicle, as I don't like raising my kilt at the front when standing next to someone else, and I always wear my sporran high up, so it isn't in the way of that anyway. As for the other thing, I just gather up the kilt and tuck it, although I do remove my sporran. As for a kilt belt, I don't wear them, but I suppose I'd take it off if I did.
