A Kardashian Kostume Kontest: Kim vs. Khloe!

Both Kim Kardashian and Khloe Kardashian showed their true colors last night.

Each sister dressed appropriately for Halloween, with Kim (seen below with boyfriend Reggie Bush) donning the outfit of a 1920's flapper. No shock that this former amateur porn star would channel an era where booze and sex flowed freely.

Khloe, meanwhile, dressed as a police officer. As someone with a drunk driving arrest on her record, it makes sense she'd wanna appear on the right side of the law whenever possible.

Which sister's costume do you prefer?
