TabbyTurmoil thank you, that is so helpful.
Women's clothing is generally not at all practical or hard wearing. Women's shoes (clothes and shoes often worn by some women) make walking and running hard/harder. Strappy sandles can cut into feet and be uncomfortable. Fluffy mule slippers make it easier to slip over, IMHO.
Women's clothes don't usually have pockets, maybe because they spoil the line of the clothes. Women's tops are often low or ride up revealing mid drfts etc. Tight skirts and tight trousers reveal bums.
Who is this for? I think it is to show women off, to make us decorative. Men's clothing (shoes and clothing generally worn by men) does not usually follow this pattern.
So this is all so different from traditional men's clothing, which along with unisex clothes like t-shirts and jeans and trainers, makes movement easier and simply clothes the body.
So when people chose traditional female clothing it's fine but it isn't gender or sex neutral. It comes with a history.
The idea that he thinks below the waist he is gender neutral is preposterous. He knows what he has chosen and why. It's not gender neutral at all. If that was what he wanted, he'd go to work in t-shirt or sweater and jeans and trainers like many of us do. But that would not get multiple pictures on the internet!
