That's the great thing about USA Kilts, you give rocky the measurements and that's the kilt you get.

If you want the waist on your navel, measure your waist at the navel and measure the length from the navel to where you want the bottom edge to be and that's how big your kilt will be.

I have worn a USA casual to a wedding and it was fine. Of course I was the only kilt there and no one would have known the difference anyway.
