There is a natural tendency to favor a tartan that you have a connection to, whether it is lineage, or history, or personnel experience. There are several tartans that I like, just because I like them. For example I wear a Gordon, because my Great Grand father was a Gordon. I wear a Clark/Cleric because I am a minister. I wear a Irish Saffron just because I like it, the same can be said for my Royal Stewart and my Buzz Kidder X kilt.

In another thread I am asking advice on two particular tartans, one that is Clan related (Lindsay) and another that is family related (Birse, a Sept of the Lindsay), of the two I have a slight preference to the Modern Lindsay, simply because I think it is a really beautiful tartan.

That being said, I also have on "order" a Scottish National Tartan in Autumn hues, because the material was a good deal, and the tartan itself is very good looking. When it arrives I will wear it with pride; made by a friend, a friend made on this forum.

The long and short of it is; wear what you like. If there is a sanguine connection and you like it so much the better. If it is an affiliation like an Armed Forces or professional (firefighters, law enforcement) association, here here. If the only connection you have is you simply like the tartan, well that's wonderful as well.

I hope this helps.

Cheers
