Paz de la Huerta is known for being a hot mess with a questionable sense of style, and last night was no exception.

The 29-year-old actress (yes, really -- that's the face of a late twentysomething) attended the Nylon Magazine bash at the Chateau Marmont on Monday night, and we're not sure if she was doing some Memorial Day partying before this or what, but girlfriend has definitely seen better days!

The former Boardwalk Empire starlet skipped the eye makeup and slathered a bunch of nude gloss on her lips, which are looking fuller than ever these days. Paz wore a bra and a Borat-style monokini, and we're dying to know how the garment looks under her ripped jeans -- I mean, it can't be comfortable!
