10. CIARA AS STORM FROM X-MEN

Ciara looked exactly like Storm from the X-Men series at her Halloween/25th birthday bash at Haze Nightclub in Las Vegas last Friday. The singer wore a killer black leather bodysuit, complete with a bleach blond wig and crazy white contacts. We applaud her attention to details!

8. JWOWW AS A SCHOOLGIRL

While her Jersey Shore co-star Snooki dressed as a pickle for Halloween, JWOWW brought us back to the "...Baby One More Time" days when she attended a party in Atlantic City on Saturday in this sexy Catholic schoolgirl costume. JWOWW looked red hot in her white top, plaid skirt, and pigtails. We love the idea, though we probably would have picked something a bit more modest.

7. KIM KARDASHIAN AS LITTLE RED RIDING HOOD

Kim Kardashian dressed up as Little Red Riding Hood for Heidi Klum's Sunday soiree, but true to the fashionista's style, she made the famous fairy-tale figure supersexy! The ruffled white peasant top, black corset, and shiny red pumps were such a pretty, modern take on the classic character.

6. AUDRINA PATRIDGE AS BEETLEJUICE'S GIRLFRIEND

Audrina Patridge hosted a Halloween party on Saturday at the Bellagio hotel in Las Vegas. The Hills star dressed up as Beetlejuice's girlfriend (boyfriend Corey Bohan was Beetlejuice!) in a black corset and striped skirt. We love how her dark makeup took the outfit over the top.

5. MISS UNIVERSE 2010 XIMENA NAVARRETE AS THE SOLAR SYSTEM

Miss Universe Ximena Navarrete had the universe on her mind (get it?!) when she dressed as the solar system for Heidi Klum's Halloween bash in New York last night. We loved how intricate her headpiece was, and even Ximena's black outfit stood out because it was mostly sheer. Bravo!

4. BRAD GORESKI AS TAVI GEVINSON

Brad Goreski, ex-assistant to Rachel Zoe and stylist, paid homage to another stylist when he went to the Lanvin Halloween Extravaganza in New York last Friday: 14-year-old Style Rookie blogger Tavi Gevinson. Brad looked fantastic in his purple wig, gray grandma sweater, and Tavi's signature black bow. You know how the saying goes: Imitation is the sincerest form of flattery...

3. ANNE HATHAWAY AS A LEOPARD

Anne Hathaway attended the Lanvin Halloween Extravaganza Friday in New York City in a leopard print blouse and pants. We are HUGE fans of leopard print, and Anne really dressed up the pattern with a blue mask and bold earrings.

2. HEIDI KLUM AS An ALIEN TRANSFORMER ROBOT

Heidi Klum is famous for her annual celebrity-filled Halloween party, and this year's event was no exception. As the night's host, Heidi definitely had the most elaborate costume, which was designed by Martin Izquierdo, the man behind the wings Selita Ebanks wore in Kanye West's 'Runway' video. The supermodel arrived in a red and purple robot outfit, and her shoes had 2-foot high extensions. Plus, check out that purple face paint and flaming red hair — that's major dedication.

1. CHRISTIAN SIRIANO AS A DANCING FEATHER DUSTER

Beauty and the Beast was the inspiration behind the dancing feather duster costume Christian Siriano wore to Heidi Klum's Halloween bash Sunday in New York City. The Project Runway winner said he made his interns design the outfit. Lucky interns! This is our favorite of the night.
