I'd really love to have some sort of fashionista NPC whom is just a collector of all gear in the game whom which you can go to to "try on" but obviously not keep or buy from. This includes dungeon drops and so forth. So we have a way to look at what is possible to glamor before the struggle of trying to obtain it. I like your idea of the collection book, or at least some other means of storage that maybe could steam off this.
