The socks made up for the school girl outfit for me, if this actually went down, those would probably have been left on. I'm probably in the minority, but I'd like to see more realistic looking models. We all know these are staged, but there are a lot of girl next door fans like me who don't really click with the leather and latex clothes.
It is so much easier to suspend disbelief when the model is not wearing stripper shoes, so this one worked on that level. I also liked how her body and feet accumulated some dirt. Again added to the believability of the whole thing.
