I checked out the Jacobite outfit and it was FINE! The only thing that was "period-ish" was the Jacobite shirt (I think that's probably why you called it a "Jacobite" outfit). If you would have thrown on a white button down shirt and a solid black tie, would she have been so offended?

Ask her if she'd give the same reaction to a Muslim woman wearing a dashiki to the cinema. All you're doing is expressing your culture and heritage and there is NOTHING wrong with that when it's done tastefully (which you did).

I would add to Blu's profile by saying that she is VERY insecure about herself and probably has low self esteem. She feigns high self esteem and confidence by trying to push her opinion on others, but inside, she worries tremendously what others think.

Yes... Feign is my $.50 word of the day.
