I purchased the Twilight (blue tint) and the Caviar (black).  This is the first time I purchased clothing from Amazon.  The quality is excellent and the same as you would find in a department store.  I also own the other two colors.  These pants fit perfectly, feel great, and give off a slight sheen.  The greatest feature is the easy care.  Just wash them, put them in the dryer, then hang them up with no wrinkles.  If you are serious about your look and attire then you won't be disappointed with these pants.

Update 11/17/15 - I just purchased the Fir color in these pants.  Awesome color with greenish brownish hues.  Now my favorite color.
