Very smart look, OC. I can second this advice as my waistcoats are from Burlington's and Men's Warehouse. Both have points, and they end a good couple of inches about my sporran.

Might I ask where you got the waistcoat? All the stores in my area don't seem to carry a collared waistcoat.

I also like your choice in photograph companions. The Spartan there has a number of complementary parts on the armor to your outfit. Buckles on your brogues? Square plate on the instep. Waistcoat? Breastplate. Gengarry? Crest on the helmet. Glasses? Mirrored Face plate. Perhaps the Spartans are 2620's Black Watch?
