Paris Hilton Goes Commando in Sheer Dress [PHOTOS]

Paris Hilton turns 33 next month, but we're happy to report that the socialite and hotel heiress hasn't erred on the side of caution or modesty as she navigates her 30s.

At a pre-Grammy party (Jan. 24), the reality star and aspiring DJ wore a black dress with a sheer hip panel that let us know she went commando and wasn't wearing any underwear.

Get a look at her intentional wardrobe malfunction below.

Paris rocked a suicide roll atop her head, but no one was looking up once they got a load of what was missing down below.

Peek-a-boo. Check out that hip bone. She is in great shape, and she has an "inny" belly button.

We see London, we see France, we see that Paris ain't wearing any underpants! She left nothing to the imagination.

Undies? Who needs undies?

Whoa! Daring, daring, daring.
