JWOWW geeked out for Halloween by dressing up as, obviously, a geek, at a Vegas Halloween bash on Saturday.

The newly engaged “Jersey Shore” star usually makes it a point to wear something super sexy for Halloween, because just like all celebs out there who have resorted to plastic surgery to improve their figures, JWoww simply cannot waste any opportunity to flaunt her silicone-enhanced body.

But surprisingly, when the reality star turned up at the Chateau Nightclub and Gardens at the Paris Hotel in Las Vegas to host their Halloween party with her hubby-to-be Roger Matthews (who was also dressed as a geek), her entire body was uncharacteristically covered up in a geek-tastic costume composed of black, thick-framed glasses, a gray button-down shirt, white suspenders, pink and blue plaid trousers that were a couple inches too short, a pocket protector, argyle socks, and black Coach high-top sneakers.

While working the red carpet, JWoww also showed off her engagement ring, which she received from Matthews last month after a unique skydiving proposal.
