When I first got into this kilted thing, I had a hard time adjusting to the higher waist of the kilt. I, now, wear them at 2"-3" above the navel, just below my rib cage, and I feel more comfortable. That height is more traditional, and it puts the kilt at just above the knee cap. But if the kilt slides down a bit, after a day of wearing it, the kilt still touches the top of the cap, which is totally acceptable.
