Wrinkles in clothes etc
 

I'm having problems making my characters clothes look realistic, ie. the natural wrinkles and the way they sag etc. Does anyboy have any tips etc or possibly tuts?

TY.

Ive got the book Maya secrets of the pro's, that goes in to cloth ans having it interacting, but i've not tried it so I cant comment, I got it off amazon for 12 or 14 quid.

Anyone else? I've had a quick search on amazon but apparantly it isn't stocked. Cheers though.
