I live and work in a very casual environment, so my comments on this are probably moot, but for me, it is more related to temperature than anything else. I happily wear dresses and skirts without hose all summer. And in winter, I most definitely wear hose or tights. To go bare-legged in winter in my climate is the height of seasonal foolishness. (Confusion is not the word for it!)
I do tend to wear midi skirts/ dresses and that probably plays a role in my comfort level. It is not as if I am revealing a lot of bare leg.
Yet, I also wear sandals and bare arms. And as my grey hair attests, I am not young.
I don't mind wearing hose -- I actually find them less constricting and more comfortable than leggings (albeit more fragile, at least the sheer kind). And nude sheers may seem like a fashion faux pas to some, but I don't feel that way about them -- I'd wear them in winter to a dressy event, for sure. But I have to admit that I wear dresses and skirts far more often in summer because they feel more comfortable without hose and I'm awfully glad for the option not to wear stockings! Especially since my summer climate is hot and humid and I don't have AC.
I agree with those who suggest you might try microfishnets. They run much less than regular hose and add an interesting element of texture.
