Here is a nice example of such folds in a painting by Gozzoli...

The Chainary fold refers to the fold held by two fixed points such as a robe draping between two kness but here you can see all the folds look like chains or ropes draped across the volumes of the figure implied beneath such as the arm. The puckered cloth is "projected" with high light and then set up from the base volume with contrasting shadow "creases".

What is more dificult is dealing with patterned cloth... there are Photoshop tutorials for creating a waving flag effect where the pattern of light and shade used to create the folds is then used as a mask for a displacement filter or the "liquid tool" so that the pattern can be offset to conform to the folds... people also use that technique to get things like tatoos aplied in post work to conform to the volume they are supposed to be applied to... e.g. to get the tattoo to conform to the curve of contour on a shoulder for instance... but that pattern stuff is tricky.
