Outside the Highlands, could untraditional be a new tradition?

Without bashing Traditional Highland Civilian Dress (THCD), what other styles of kilted dress are becoming or have become new traditions?

After having read various threads on this site, I'm starting to get a better grasp of what THCD is. It seems, however, that many kilted folk do not fit into that mode...

Whether this is a question of people not knowing about traditional conventions or people knowing the "rules" before they break them, there is a lot of variation! Perhaps there are regional styles of kilting other than Highland? I have a great appreciation and respect for THCD but for the purpose of this thread, let us say vive la différence!

Could the box pleat kilt (a revived, historical style) become a new tradition?

In hotter climates, what accommodations might become standard?

How about traditional-ish outfits but with things like tartan flashes and ties, general concern for matching colours, flat caps, wearing tartans other than that of one's clan, P/V or acrylic, semi-dress sporrans, etc?

Are there relaxed dress codes for casual/formal? Say tee-shirt, boots, and scrunched down hose for daywear and only as much as jacket and tie for evening wear?

Could modern kilts (Utilikilt, Alphakilt, Sportkilt, USAK casual, Bear kilt, etc) be the new jeans of the kilted world?

Other untraditional traditions?
