Personally I use an elasticated belt... but I have managed to get that twisted sometimes... heh! heh!
Probably a good idea to wear them untwisted, no point making yourself a target if you can avoid it. You may be able to evolve a way to get them on without twisting... but I don't have any ideas. Maybe have them hanging from a coat hanger and climb into them from below... Wallace and Gromit style.
One of my big problems is organising those little dobbly things that tighten/loosen things like that. I always tighten instead of loosening and vice versa... never can get my head around it.
