I'm with Jamie there, the cumberbund was bothering me a bit as well.

Shriner, Rather than put the satin stripe on the side of the leg, consider putting it down the apron edge. Visually it's a more appropriate location. If it were on the side, my eye would be expecting to see a stripe on every pleat Otherwise I'd leave the black kilt as is.

I've just always really liked the Humphrey Bogart Tux look and believe it will translate well into a kilt.

Edit: I like the jacket open rather than fastened also
