More Room - I'm not talking about larger sized robes but rather no more void storage. Once an appearance is learned, it is added to your account wide armor and weapon database. Any character on that Battle.net account of the proper level, class and armor type can access that item for transmog. So you don't have to farm your favorite chest on all your plate wearers and stuff it in void storage.
Saved Outfits - You can save your favorite outfit. Once that's done you can apply it in one move rather than changing each individual piece. You also have the option to save an item for a specific specialization.
Old Hat - Remember that one chest you got from that one quest in Vanilla that took you three months and it had that cool graphic and you finally, like, vendored it two years ago and bewailed the fact you'll never get it back? It's back. Not the chest but at least the looks. Old quest item graphics are automatically in your wardrobe.
It's New - When you add an item on one character, it will update when you log into a different character. Each new item that has been added will be highlighted so you won't have to dig forever to find that new piece.
Make it Disappear - There is also the option to make your helm, cloak and shoulders disappear. Some helms are just ugly, sometimes I want to see the back of my armor, sometimes those shoulders just...get in the way! Well now they can be turned invisible. Sweet huh?
That's just a few highlights. There are some quirky ins and outs I've managed to find such as an item showing that's available for a character but then not being able transmog it. All in all it is a HUGE improvement over void storage. I was simply hoping for a larger closet but this is a much more elegant solution than adding a void storage tab!
