I have the 590 in twilight, and love them.  They fit me perfect, without any areas where they are tight or slouchy.  But the retailer I ordered them from only had the one color, and it's a little washed out looking.  So I was excited to find the style and cut that I like in a dark blue wash, but when they came they didn't fit like the others do-they are much smaller.  And the back pockets are different from my other 590s.  They have a faux flap and a button on them, but they say 590 right on them, but they aren't like that in the picture.  I almost wonder if they were mislabeled-they seem to be a full size smaller than the ones I have in the same size and cut.  Could be a fluke, but just be aware.  I think I will be returning them.
