My fantasies revolve her at least starting out with white panties or opaque white pantyhose. Preferably well worn, but no holes. I like the stains of good wear.
But as I've said in recent posts, I'm disabled, so many positions would not work for me. All I could reasonably do with her in pantyhose is rub her clit and maybe finger her vagina (which is certainly a thing I'd want to do).
I do have a bit of a pajama fetish (which goes beyond "lingerie", strictly speaking, I think). I like a girl in a simple white nightgown with some frill and ribbon, and either the aforementioned white opaque pantyhose or maybe booties (kind of an AB thing, maybe, though I never saw myself as such). If it were panties, she could easily facesit. Footed pajamas, either one or two-piece, are another fetish I have from when I first discovered sexuality.
But in reality, those might get in the way too much. I don't know (any ABs want to chime in?). I guess if it were two-piece footed pajamas, again, there's the hand in the woman's bits. I admit, there's something special about imagining the girl cumming in whatever fetishwear I have her wearing. And there's being breastfed, which is always a huge fantasy. And she could lay down on her back and a could perform cunnilingus if she pulled down her bottoms.
If it were a one-piece, she could unzip herself partially, and I could be breastfed, and again, a could manually stimulate her.
And nothing gets in the way of a blowjob (except the medical mask that is my main fetish).
Well, OK, now that I write all this, I guess there's nothing too limiting about all this!
