The first FK kilt jacket is on my sewing table right now.
I'm doing it from a nice caramel brown cord fabric that I had around.

Yes, the jacket will be very like what you describe. Just a little older in style than those in the pictures. More like if Calvin Kline of the '70's was blended with Savile row of the '60's and a little touch of Bogart of the '40's thrown in.
Very simple, classic, timeless.

I have a source for the most beautiful Donegal Tweeds. In browns, grays, and charcoals.

patience my friends, fullness will.
