Now that we have rules, we can test them......?
I can tell you this much, the "prefered" (sounds a little snooty here) hidden nudity pic has the objects at some measurable distance from the body parts being covered.
But maybe this is just a "hidden" vs "covered" distiction though, and this thread is actually for both. So in otherwords, although most of the pics you just posted are covered, not hidden, they are still OK to go here.
....except for the naked cowgirl pic, IMHO, which is a pasties pic and pasties are "worn" (meaning she does not have to physically hold them in place with her hands). And also the pie plate pic, which is an improvised clothes pic.
The tie pic I would say is covered because even though she is not holding it in place with her hands, she would have to eventually if she started to move around. Also, the other boob is hair covered and thats OK. IMHO again, if she were to use some tape to hold the tie in that position, it would then be an improvised clothes pic (except for the hair...)
Finally, we have the suds pic? mmmm.........lets see, where did I put my rule book....?
