me likey! i haven't seen one IRL yet, but it sounds like a functional yet stylish bag. it has a lot of vachetta on it though so if you're nervous about that i would consider the damier. i don't think that you can go wrong w/ either though!
i was actually lusting over the mirage griet (but not the one with exotic leather handles) and was able to see one irl over the weekend. i changed my mind because it was huuuuge for me. i tried putting it over my shoulder and my arm stuck out so odd, and when i put it on my arm, i could feel how heavy it would be and it was empty at that time. but it's still lovely, the shape and push lock is soo nice, but i guess it depends on your frame and if you think you'd be able to carry it well
