Sorry, I meant by someone unaware of the meaning of the kilt, which in reality would be the majority of people.
If I was wearing one, they would see me in an orange kilt. I know that before I was more aware of the history of kilts, I would have assumed that this kilt was associated with the orange order in some way. Both due touts colour, and it's association with the Ulster-scots and Scotland.
Nothing to apologise for. I find it quite interesting that, in the same position as you, I would have assumed precisely the opposite and thought it was connected with Irish Nationalism in some way! The assumption would probably have come from some subliminal connection between the saffron colour of the kilt and the orange in of the Irish flag.
