How to draw cloth in photoshop for Uv maps?

I have mastered skin shading. And painting muscles. But drawing cloth like a dress or similar. I just can’t do it. Is there some kind of trick to do it in photoshop?

If there is please tell me what it is :smiley:

obvious quesation would be, cant you just use a cloth texture?

No I need to draw it, I thought of a technique in photoshop. Making a new layer drawing out the wrinkles that appear in the cloth and then using some kind of blur metod to smooth it out. Not sure if this will work though…
