shirt/tee colors to wear with kilts

[CMcG]

My girlfriend isn't Scottish, but she was a Catholic schoolgirl for many years and a tartan kilt-skirt was part of her uniform. Now that she's a "civilian," she still likes to wear a kilt from time to time. My mother has also been known to wear a tartan skirt. I'm making no claim to authority or traditional authenticity for their attire, but I think they look good

Here are a few pictures for you.
