This very informative thread has had a major influence on my dress for the day. It's a tight-rope balance between the occasion - National Tartan Day and the (non) event - hanging out with my brother at the cigar store where he works part-time. The cool weather and my limited arsenal were also factors. No way to take pictures right now (will do that later) but the final ensemble consists of my Scottish National casual kilt with DIY fringed flashes, navy popcorn hose, brown belt (w/ brass buckle), shoes, sporran and strap; light blue Oxford cloth shirt, no tie, and tweed Braemar jacket. I may shed the jacket inside.
Thanks to all who have contributed.
