For women, wearing tartan is, I think, a matter of style and conforming to local norms rather than 'tartan rules'.

I can't see any sort of tartan skirt of suitable length and style being thought wrong.

PS I would admit to a certain element of cross dressing when wearing my kilts, if challenged on the matter, but so far, no one has even commented on them being fastened the wrong way round or the like. I think it is much less of an issue here than in the States.
