Exactly. If a woman wants to wear jeans, it's OK. Or slacks, or a skirt, or a dress, or shorts, or leggings/yoga pants these days.

What choices for bottoms do men have that aren't trousers? There's shorts if the weather's warm enough (though there seem to be a bunch of weird men out there wearing shorts in freezing weather for some reason), but that's it.

Don't forget the colors. Dress too colorfully as a man, and people think you're gay. So we usually end up sticking with darker, solid colors.
