What would buy if you were a bazillionaire? Paris Hilton spends her cash on a boatload of Halloween costumes! The celebutante bought 14 different outfits for the spooky holiday, a source tells Us Weekly, which includes disturbing Alice in Wonderland, a pin-up girl, a trashy girl scout, and a skanky sailor. But they didn't go to waste! On Wednesday night alone, she wore two of the costumes -- a sexy prisoner (with the word "jailbait" on the butt) and a scandalous military girl.

The item tying her costumes together (besides the obvious hoochie theme)? Creepy contact lenses. (Don't look at her, kids -- you might turn to stone!)
