How is this even a question? Lol! Peyton, hands down, had the best costume! Hilarie rocked that thing. My next would be Lucas if had gone with the pirate - he looked hot in that costume. Nathan was hot as Batman but he was a little too fully clothed for my liking. Haha! Brooke's was so freaking ugly - from the wig all the way to the actual costume. And she made that - Hmm... Yuck, what were the writers thinking?! Haley - while Joy looked amazing, I didn't like her going as Sandy. It looked way too desperate.
