Trying to expand our clothing choices by arguing that women should not have them is unproductive and does not help anyone. As some have said you can actually go out in a skirt or dress as a man if you want in most western countries. I have often worn a skirt as a man in public. Only once have I had a negative reaction - a woman shop owner ran her eyes up and down me with a withering look and shook her head. I found it amusing not upsetting - and that is as bad as it ever got. Even schoolchildren walked by without paying any attention to me.
I remember back in the early 1970s women liked wearing jeans and had to buy men's jeans because they didn't make them for women then. They had to pull the belt in tight to make them fit.
The solution is in our own hands. To change attitudes men have to be seen as much as possible in womenswear. There is a massive difference between a man wearing a skirt, tights and heels and one wearing false boobs, make up and a wig and presenting as a woman and we should not pretend otherwise. Both should be OK in our society and - you know what - they are - it is just a matter of turning tolerance into total acceptance.
