Why do some women wear pantyhose year-round?

When it comes to pantyhose, many people immediately assume it's just to seduce men.
Actually, pantyhose really don't have much practical utility. They don't provide warmth, they don't offer sun protection, they don't protect your legs or knees either. They're thin as paper and tear easily with the slightest friction. Pure consumable product. Wearing them in summer is stuffy, hot, and uncomfortable. Even using the bathroom becomes a hassle.
Honestly, the first thing I do when I get home is take them off.
But whenever I go out for work, I have to wear them. When meeting clients, I have to wear them. On dates, I have to wear them. And they have to be black.
Don't give me that excuse about preventing varicose veins—that's all just an excuse. The real purpose of pantyhose is to shape your legs and attract attention from the opposite sex.
