During the winter, and when it's chilly in the fall and spring, my wife wears pantyhose every day, even under her dress slacks and jeans. She swears that, like long underwear would, they help keep her legs and butt warm when she wears them under pants.
When it's not as cold, she will sometimes wear thigh top stockings instead of pantyhose when she is wearing a dress or skirt. When it is warm enough that she doesn't get a cold draft up her skirt, she wears the thigh top stockings most often. She likes how she doesn't have to pull pantyhose down and back up every time she goes to the bathroom, and she knows how much I love to undress her, leaving her stockings on while we have sex. The stockings are the stay up kind that go all the way to the very tops of the thighs, so the stocking tops don't show when she is sitting down. If she is wearing a mini skirt when we have a date night, she will wear crotchless pantyhose for easy access for me later on. Plus she doesn't want to take the chance that stocking tops would show with the mini skirt while she is sitting down.
When the weather turns warm, she still wears pantyhose or thigh tops when she wears a dress or skirt suit to work. But she goes for the thinnest denier, and only wears the "nude colored" or light tan variety. When her legs tan up in the early summer, she will go with no nylons with her work outfits until early fall, when she starts wearing them again. She has silky smooth, flawless skin and well toned thighs and calves, so she looks great without nylons, too. Every pair of nylons she owns have a lot of lycra in them, so they are very shiny, and she has many color varieties. Different shades of beige, suntan, nude, off black, and grey, plus some pairs of white, red, pink, purple, and emerald green for "special occasions". Most of the time she buys hosiery made in Europe. Their hosiery has more lycra blended in with the nylon, not only making them shinier, but also more durable than the American made variety. They cost a little more, but last a lot longer and are more resistant to runs. Whenever we vacation in Europe, she will stock up and stuff her suitcase and carry on bag with as much hosiery as she can fit! And if she needs some more before we go back to Europe, she can get them online.
As far as garter belts and stockings go, she will wear them with a knee length loose fitting skirt for a special occasion, like a date night. But never with a short or tight skirt. She doesn't want the garter bumps or stocking tops to show. She saves that look for a private show for me at home. ?
I am definitely a leg and ass man, and I also have a major nylon and spandex fetish, so I am very lucky that my wife loves to wear both. She has an entire dresser drawer packed full of neatly folded pantyhose, crotchless pantyhose, stockings, and knee highs.
I think it's sad that these days women hardly ever wear pantyhose or nylons anymore. In my opinion I think it just gives a more polished, finished look, especially in the more formal office environments. My wife has told me that she is part of a small minority at work that even wears nylons, except on the coldest days. When my wife and I travel overseas, we notice that most European women still wear nylons with dresses and skirts, even in summer. I guess it's just a lot more common for women to wear them over there.
