I ordered one pair of these to see how I liked them.  They were very creased and wrinkled when I took them out of the package and showed no sign of "hanging out."  So I took a warm (not hot) iron to them with the help of a spray bottle with water.  The creases came out and they hang beautifully.  I have ordered a second pair for the other bedroom. I wanted dark denim and had no luck.  These work very well.
