Let's get one thing straight: I actually don't dislike what either one of them is wearing.
The long hair and the flowing sleeves and goth-y eye make-up and impenetrable expressions make them look like priestesses in an arty film set in the Middle Ages, during which one of them would spend a lot of time flitting around a turret holding crystal breakers full of mysterious and possibly dangerous potions. She would wear shoes lined in fur, and a crystal around her neck. The other would play a sort of charismatic, seductive temptress who sleeps with men in order to get a sample of their DNA so as to help her sister create a potion that will allow them to rule the world. She would spend a lot of time naked, and carrying a serpent. Men would know that she was likely to kill them after having her way with them, but they would take off their capes and doublets and submit to her wiles anyway. It would all be very dramatic, and the absolute opposite of what you would expect from Michelle and Michelle Tanner. I kind of like it, even though I can think of several reasons why I shouldn't.
However, I DO have a comment: Ashley's new hair color has thrown me for a loop. Newly Brown Olsen IS Ashley, right? It took me twenty minutes to figure that out. Give us a smile, Brown Olsen. It can't be that bad.
