There are skirts and skirts. In cold weather there is nothing nicer than a great long floor-sweeper with a couple of warm underskirts. You walk around in your own bubble of warm air. Feet and ankles may get a little colder than in trousers, but the mid and upper legs are a lot warmer. Curl up on a sofa and your feet get warm too.
When working on a lathe, there are no exposed moving parts below waist level so it is safe to wear a long skirt - which keeps the swarf out of your socks and shoes.
[...]Those are the ones you notice, but the ones that dress and behave sensibly don't get noticed. There is a comparison here with teenage girls: they can wear makeup and revealing clothes for the first time in their lives, so they go a bit too far. Then they find out what suits them and settle down to be just ordinary women.
Some men have strange ideas about what it means to be a woman and think feminity is all about glamour, sexiness or extreme effeminate behaviour. They get mixed up with transwomen (in their own minds too) but usually don't ever transition.
