You do see a lot more women in kilts, they are more apt to be in a mens trad. than a ladies kilt skirt these days. I think it's fine in pipe bands but like the more shapely fit of a kilt skirt. There are a few kilt makers (Canadian Casual Kilts makes both in all tartans and solids-including denim) that will make a kilt for women whether it is a trad. style or a more women friendly hip hugger style.
More women find the fit of the hipster more appealing because it sits more on the hips where jeans sit where most men like the kilt to sit a little higher or even higher on a full trad.

You can get them whether the men here like it or not. It is first and foremost a mans garment but my wife looks very good in her hip hugger mini. I'm not going to tell her not to wear it!!.
