I like those and would have considered them for the GPOP but needed wide leg or flare because one of my goals is always to cover my necessary gym shoes a bit. I'm glad they worked for you!
I have the same issue about navy, but over the past few years I've rejected quite a few tops I really liked because they were a navy background print and I thought they would look weird with black. I like solid navy and black together, but print navy with black seems less intentional and more clueless, to me at least. What I'm saying is...this may be the basis for you branching out into some more navy items! I am waiting to life test my new EF pants and if they pass I may be getting them in navy too!
