Thanks for the elaboration MacLowlife.

The Spencer jacket seems to work with the tartan waistcoat... maybe even better than the white one! And I've tied the bow tie with a narrower horizontal spread. Also tried to make it a more non-chalant knot, as per Irish Jack O'Brian's suggestion.

I'm still looking for a suitable pin to put on this kilt but used a plain, safety pin style for the moment.

Without further ado, here's the pic:
