Straight men wear "kilts" or "sarongs". If you think either is not entirely and unarguably straight and male I would invite you to repeat your views in certain places....

Or a dhoti if it’s hot out.

I live in a place in North America where it is not uncommon to see men in kilts. Still, you can safely assume that anyone you encounter in such attire is attending a formal function or cultural event. While it may be gendered as masculine, it is not a norm for everyday dress.

Sure. But I would similarly invite you to go up to a straight Scottish male in traditional attire and ask if they are wearing a skirt :)

Women in Paris were only legally allowed to wear pants in 2013.

There are lots of ridiculous unenforced laws like that; it doesn't tell you much.

There sure are. I wish there was some clause though that any law not used in a court of law for say 30 years, has to be actively renewed to not expire. From time to time, malicious actors try to abuse such laws.

I like that idea because it'd take a lot of teeth out of "this won't hold up in court but we can still harass you with it" type laws.
