Sewn down pleats?

[OC Richard]

I should have made it clear that the optional sewing down referred to the portion of the kilt a bit further down. What are your experiences with correct creases getting undone for example by sitting against the crease with your buttocks, on normal kilts? Just wondering the added benefit of continuing down the sewn part a but more.

I've not heard of sewing the pleats further down than the point past where they're sewn down, which I suppose is an oxymoron.

If you sew down the pleats, they don't function as pleats any more. It doesn't make any sense to me.
