Looks right to me too... the guide i was given when ordering my first kilt many years agi was the top should be 3 fingers below the ribs... which pretty much is the same as 3 fingers above the navel... at least in my case.

I do seem to recall the distance from the top to the hip being measured too, which would make sense to me in case you're not a generic body type...

If you think it's too high then you might want to try one of the casual kilts which are designed to fit with a much lower jeans waist... less traditional, looking, but still nice and available in all the traditional fabrics etc.

I'm not sure if matt's box pleat haa a lower waist, but from memory it strikes me as having one
