Nude mods have always been a marginally less creepy affair in Elder Scrolls games than elsewhere, because that kind of attention to detail also results in a dramatic improvement to Betheseda's mud-faced characters. That is to say, folks want to upgrade the body meshes, and it just so happens that the best body meshes are the ones without underclothes, generally.
Although sometimes that's less true for male models, simply because they have, ah, a slightly higher polycount without underwear, so there's a little more work involved there. It wouldn't be an issue except that the Elder Scrolls games apparently have moderately strong female and gay player bases.
This looks like a good rundown of the various female mods; you'll want to check for compatibility of any other mods you may be using that add armor, faces, and the like. I seem to recall that
Robert's was the de facto standard male mesh replacement.
