As a total package sort of thing, the chick playing Doreah is awesome, but on straight boobs the chick playing the Sansa actress has some good ones for sure. Mel boobs also excellent.
I understood this to be a decision based solely on the qualifying titties. Not to be confused with 'overall hotness', skin tone, prettiness of face, crazy-to-hot scale, etc. Pure tits, I'm taking #4. Oh hell, I'd welcome all of them, but I voted #4.
