Bumping because I just remembered another one: Keep the shoes on! Real Porn Stars Fuck In Their High Heels.

It makes their legs look better, and it just gives a wonderfully trashy edge to the whole scene to see the bitch nude except for a set of 5" stripper heels. Bonus points if there is wear and tear on them which makes it obvious she wears them on stage.

Not a foot/shoe fetish thing at all, more a leg thing and a preference for the talent to look as whorish as possible. (although the Girl-Next-Door trying to wear heels that she can't walk in is also hot.)
