It's been a while since I read pop-up books, but Maison Martin Margiela
's metallic bag brings me right back to their 3D thrill! This space-efficient style folds into itself
for ultimate efficiency: collapsed it takes up hardly any room in my closet, but at capacity it could fit much of said closet's contents. Pop-up books may be for a younger set, but this bag's much more fun!
$1,680; at Maison Martin Margiela stores
