Every fashionista worth her Louboutins cares as much about a book's outfit as she does about its content. This pursesized encyclopedia dons a cloth cover stamped with shimmering silver foil and a satin-ribbon page marker.

Equally snarky and stylish, this insider's guide is sure to be on all of this season's best-dressed lists.
