Dakota Fanning attended the 13th Annual Dream Halloween Benefit as Snow White. I don't like making fun of children, but this costume is freaking me out. [Source]

Not surprisingly, Paris Hilton's Halloween costume allowed her to walk around in lingerie (although, I guess she does that when it's not Halloween, too). This year, maybe in an homage to her recent run-ins with the law, Paris is a police woman. [Source]

Dave Navarro chooses the not very exciting devil costume for his Halloween Lingerie and Costume Ball. I think the guy would use any excuse to cake on some makeup. [Source]

Hilary Duff is a Gypsy and her sister Haylie apparently an 80's aerobic instructor at the the annual AirParty Halloween costume benefit for the Trevor Project in Hollywood on Sunday. [Source]

Bad idea, Bill Maher. Very bad idea. In case you can't tell, that's a stingray tail sticking out of his chest. Sigh.
