^same deal here with that...particularly the sheer black stockings.... any other clothing that is transparent/translucent....even with women that ordinarily aren't what I consider to be attractive... if the body is even slightly decent and their dress is "see-thru", I can't help but get a rise from checking that out. The "see thru clothing" visual is SO goddamn hot. (*but I'm still picky about it though...there is a "see thru" thread here on the boards but most of the pictures that get posted just aren't hitting the mark for me....a lot of them are that "fishnet" stuff which is always lame, imo.)
An old friend's mom (family friends since I was a little kid) actually worked in the same building with me, and one day she had a light blue dress...only slightly form-fitting and long, but her body is ridiculously nice... and this dress happened to be QUITE transparent if she stood next to a window or certain other lighting conditions like that. Because of how "proper" she is (also very religious), this was a surprise...and actually did seem like a situation she wasn't fully aware of. When she came over to my work area to speak (small-talk), it was by the window... so I had a good view...perfect full outline of her legs all the way up, including the gap between the thighs....almost as if she was wearing a clear plastic bag as a "dress"...then a wonderful view of that backside when she walked away. In no time I was rock hard from this visual. I never imagined I would get to see her like that. Prior to this scene at the desk/work area... I also caught an incredible view on the way in since you have to go up stairs and she was in front of me, going up.... once you reach the top of the 2nd flight there's an area where the sunlight shines thru...it was so clear you could see the exact space between her thighs, and even see thigh movement with each step (full/voluptuous figure without being a fatso) I still hate that I didn't happen to have some kind of camera with me at the time, but of course that would've been stupidly risky.
Panties--unsurprisingly it was full-cut panties. She must've realized at some point (or someone let her know) how much could be seen, because on later occasions where she wore that dress, she always had a slip under it which effectively killed the visual
