What's the most stylish porn you've watched?
In still images, that would have to be Chloe Des Lysses. Maybe not the best example this. Not bothered to increase the rez.
And in video, I'd have to go with something from AlexD (for the stylish vibe) or some JAV stuff with Jun Kusanagi (for how she bends her body to present it to the camera the best way).
Not talking about lighting and shadows and such style values.
