She's so so SO in the public eye and so closely scrutinized, she kinda HAS to go small first. So it looks like a cute fashion accessory and no one questions it much. After all, she's Paris Hilton, the most superficial media-whore ever invented. As for her going larger, she may never go huge, but don't rule out going larger. She's not the prettiest thing, as her youth fades and her tits become an asset to her sex appeal, you might see her go bigger, and bigger.
I hope so.
I hate her, but that won't stop her from coming out of my tv and my internet. So she might as well satisfy my desire to see her inflate her chest.
