Personally I like the high rise of a traditional kilt. It simply feels more comfortable to me. Most of the light weight and modern kilts are cut with the expectation that they will be worn at a pant-level waistline. Whereas you can easily wear an SWK at the full traditional height without worry, and that's what I do.

I wear my SWK kilt at the same height as my tanks - approximately 1 inch above my navel. At my sides, the top of the kilt rise gently brushes against my ribs. It looks quite good according to all who have seen it, and I would highly recommend trying it out at that height.

Wear that kilt just a little bit higher and you won't need to hem it at all. Plus, there is something just secure about having a garment belted at that level.
