Actually...
... you should go for it. You see, there\'s no reason not to try NMM to portray materials that are not supposed to be, well, metallic. AS a metter of fact, the only real difference I\'ve ever found between doing colored NMM armor and regular clothing, is that the armor has to have really sharp, thin, short highlights to give the impression of hardness, while regular clothing can be done without this sort of treatment. Also, when portraying fabrics, most of us use a gradient that starts with the darkest shade suitable, and ends somewhere short of using pure white highlights. So, worst case scenario, using NMM for a satin look might be interpreted just as very dramatic highlighting.
