Sorry to post over myself

I've been doing my best Googling to find THCD daywear or less formal examples of tartan jackets... you've set a tough challenge MacLowlife! It appears that tartan jackets (with matching kilts) in contemporary times are rather dressy and also somewhat uncommon. There are perhaps more examples of either historical examples, so I'll post some of those too. Apologies if I stray too far from traditional into historical or fashion

Apparently there are some examples of mismatched tartans, which MacLl hinted at...

Here is Ted Allen from an edition of Dressed to Kilt. Tartan jacket that does NOT match his kilt:



A similar but more historical, non-matching tartan combo:


The check on this tweed is strong enough that it's almost like tartan:
