I made a post earlier about this. Here is a quick example on how I come up with my general folds and creases. I figured that a dress would make a good example, simple and easy.
The model is standing still, so there shouldn't really be any folds in the fabric, but since the model is a female, I add some lines between her breast to show that... she has breast lol. I also add more lines underneath her chest area, around the stomach area, since she has a obi-like belt there.
The right one shows her in motion, maybe dancing or running. The fabric are gently blown back, showing motion, not like she's standing behind a jetliner.
I do the sketches first, to see if the lines are good, and if more is needed or if some folds don't look right.
I'll probably post some more examples, with different styles next time.
Good luck with your art, people. Thanks for checking out the tutorial.
