OK so basically, if I am not supposed to be wearing it, I probably wont even has access to buy it in the first place.

I made reference to colors and gangs earlier. It was really about blood and crip type street gangs. But one of my ministries is the Christian Motorcyclists Association. You may be familiar with us regardless which country you live in. In the MC world clubs register there patches (colors) and if you get caught wearing a patch you don't actually belong to, or in the wrong part of town, it is violently taken from you.

I guess in Scotland and Ireland that applies more so to soccer jerseys than tartans.
