It all depends how tall you are, and how high or low your waist is. I am only a little shorter than average, but have a long body and short legs. I have to wear a Sport Kilt quite high up, or it is way too long. I have read that it should go lower, but not on me I'm afraid.

Similarly, one of my traditional kilts is cut to a 20 inch drop, and that's not a bad fit. I have others that are a stock 24 inch drop, and they are passable, but some of you would think they are a little long.
