Make sure that when you use a displacementmap you use it for every part of the body, otherwise you get cracks at the borders of the different material-zones! you can't use a bump-map as a displacementmap because it works different: A bumpmap uses a medium grey-color  as the zero or neutralheight everything darker is lower, and everything lighter is higher, when you use a negative value for the bumpmap settings it's the other way around. A displacementmap use black as the lowest point and everything lighter is higher, so when on the edge of a materialzone the  color isn't black, you get a crack. So when you want raises in a displacementmap you use a positive and when you want depths you use a negative value for the displacementmap settings.

Normaly speaking you can have only positive values in a color (greyscale) map, but I've done some experiments with combining a image map with a math-subtract node which gave so interesting results. So is it possible to make a displacement map gravity controlled, by using a N-node.

But I agree that you have to get the grips on it, it took me some to figure it out how its works,  You can make some nice details on clothing, with paintshop or photoshop without having to use a modeller.  I 'll try to give some examples and how you can use it.
