I can wear a dress to work and nobody criticizes me. I’d be really sad if I had to wear pants all the time, they’re just not as comfortable. Let’s normalize pretty dresses for dudes!
As a man I never considered pants to be uncomfortable. They are the perfect mix of range of motion, hiding the private parts. and support. Dresses, skirts, and robes seem like a nightmare to wear. You either restrict your range of motion or have to constantly worry about showing your underwear. And I would wear boxer briefs underneath by choice anyhow, so I still end up wearing pants.
I think the bigger issue is that most of us men are too lazy to look for different kinds of pants and end up wearing the same stuff year-round. Which can indeed become uncomfortable due to changes in temperature. But that issue wouldn't be fixed by having access to dresses or robes. As again, some would either be too cold or too hot.
I used to have a pretty intense not-like-the-other-girls fase in my teens, and I never wore skirts or dresses, and felt the same way you do. Then I got over that internalized misogyny and started experimenting with clothes a little, and the first time I put on a dress it was like a hallelujah moment. The most comfortable thing in the goddamn world. They do not restrict your movement at all, that's only a problem if you wear knee-high pencil skirts of stiff fabric. In colder seasons you wear leggings under them which are equally comfortable. It was so incredibly comfy I did a complete 180 and it took me 10 years to wear a pair of pants again, and that's only because the waist high mom jeans in style now are so loose and non-restricting. Any other style of pants I won't touch with a 10 feet pole.
Wear a long enough dress and you'll be fine. You could also wear a skort (which is a skirt/dress with shorts built in underneath, but from the outside it just looks like a regular skirt/dress) or just wear shorts or leggings underneath. You've got lots of options!
What are these magic cooling pants you speak of that are acceptable in a professional setting? Or are you British and think we are talking about undergarments? We are talking about trousers.
