I always see women wearing pantyhose with pants, and I'm curious - do they usually wear tights or the full pantyhose when they're wearing a pair of pants instead of a dress/skirt?
Most times when I'm wearing hose with pants I'll be wearing full length pantyhose, but when it's really hot outside I'll wear knee-high nylons to be a little more comfortable.
They are more than likely knee highs though some women do wear pantyhose with pants/slacks/jeans (which is what I do). Pantyhose helps your pants slide on/off easier and if so needed you can go commando and not wear underwear.
I my self always wear tights or pantyhose under my pants depending on the season. i see nothing wrong with it. pantyhose actually can offer some support to legs as well
What you are seeing are probably knee-highs or trouser socks. Those are the type of hosiery most women wear with pants. I happen to wear pantyhose under pants, but that is rather uncommon among women in general.
Most of the time what you see them wearing are probably knee highs, although some wear proper pantyhose under their pants or jeans. There are definitely a lot of things to be said for wearing pantyhose under pants. They slide on and off easier, they prevent the fabric from sticking to the skin, it is comfortable, makes the pants and especially jeans feel better, and of course it just feels good.
Usually woman hate pantyhose so it is probably knee high or sock that are made to look like pantyhose. I always expect that woman have pantyhose under their jeans or legging but it's quite few
