Okay, let's get this straightened-out before it gets WAY too confusing.

There's a HUGE difference between the MacKenzie Tartan... and the MacKenzie DRESS Tartan!!!

When Bubba posted his question, it was concerning the MacKenzie DRESS Tartan.

YES, the Regiments use MacKenzie but NOT the DRESS tartan. That one comes from the Scottish Tartan Authority.

Dang! I even started to get confused!
