Not many people wear a Nova Scotia tartan here in Nova Scotia unless they're in the tourist trade. I imagine because there are so many people of Scottish descent that they have their own family tartan to wear. However, the few that I have seen not in the tourist trade, over the 16 years that I've lived in Halifax, have to a man (and one woman) worn matching tartan hose with gold or dark red flashes. The ones in tourism generally wear cream hose with dark or bright red flashes.
I'm not sure I'd go with the red/white diced hose as they have a strong association with the 78th Highlanders at the Halifax Citadel. In fact, I've only ever seen the red/white diced hose on the soldiers or at a formal evening event.
