Are there any alternatives to strap/buckles on kilts?

[Kriegbert]

For personal medical reasons I can no longer independently do somewhat complex movements with my fingers, I was wondering what kind of alternatives there might be. Velcro is a last resort, surely, I wanted to explore what kinds of fastenings might be employed.

for example on my trousers I replaced buttons with zippers & hooks & eyes; for dress shirts; there are magnetic buttons that are hidden when you wear a tie etc.
