I'm not sure if the "ice breaker" properties explain the power of the kilt. Women aren't just "able" to talk to us men in kilts, they can't help it. They end up beside themselves.

I belive that your theory has merit, but I think that there is more going on with the power of the kilt than can be explained by your theory. Something magical, mystical, and far more powerful than a female's willpower!
