Skirts on Men

I did a concordance search of the word skirt in the KJV and every time it was used, it referred to skirts on men. My question is, why don’t we have a skirts only rule for men instead of women if the argument is that men and women should be dressing differently based on skirts or pants? Of course I do not hold to the dresses only argument for either men or women, but am confused as to why some contend over this issue as if there were a verse in the Bible that said that women shall wear dresses. The other question I had is why tennis shoes are okay for women to wear when they pertain to men as much as pants do.

I understand that some make the argument from a modesty standpoint, but I am not convinced that dresses are more modest than loose fitting slacks- especially if a woman is picking apples on a ladder or even scooting around on the floor playing with a toddler. Therefore the main emphasis of my question is desiring an answer for the first point about dresses pertaining to women and not to men.
