I think it's common that women find men in kilts sexy. Not all to be sure, but most.
I've had several women tell me that they find it sexy. One time in church with my wife right there!
One woman simply heard that I wore kilts (I was wearing trousers at the time because I was traveling on business) and she said she thought kilts were sexy and asked if I had good legs!


Kilts can be very dressy, but they can be toned down too. It's all in how your man wears it.
He's a lucky guy though having such support. Some of us don't.
I do, thank goodness!
