Co-stars Kate Hudson and Nicole Kidman may share vamp fashion secrets in the musical remake of Fellini's 8 1/2, but their personal styles set up more of a dichotomy. Both actresses star in the fashionista movie of the year, Nine, a movie that will send you running for your chic black dresses.

The Fellini Appeal
In Nine the stars wear their smoky and smudged eyeliner and shadow glamorously, and complete their sexy looks with glittery black designer dresses, wide fishnet stockings, big 1960s style hair, and over-the-knee boots.

Bohemian Kate Hudson
While Kate Hudson looks stunning in a yellow Dior gown or a metallic brown Stella McCartney dress. Kate Hudson manages to add glamour to simple Bohemian looks. She is one of the few actresses who could have successfully worn an orange, yellow and black print Valentino gown.

Kate elevates simple Bohemian to Boho chic by accessorizing a pair of torn boyfriend jeans with textured suede. She adds hats, bold jewelry, a pair of comfy boots and designer handbags to her laid-back Bohemian style. A stack of silver bangles, colorful sunglasses and styled hair complete her chic Bohemian style.

Glamazon Nicole Kidman
Statuesque Nicole Kidman dresses for the red carpet even when there isn't one. She is not an actress you'll find unkempt or even going Bohemian casual. Nicole Kidman is a vision of seriousness, in contrast to the playful fashion of Kate Hudson.

The walking mermaid's dresses look painted onto her lean figure. Despite her natural height, Nicole Kidman always as the perfect pair of heels to pair with her designer gowns.

In the movie Nine their roles are slightly reversed, with Nicole Kidman playing the actress/muse and Kate Hudson takes on the more serious role of fashion journalist, Nicole Kidman remains the glamour queen and Kate Hudson's wardrobe exhibits her signature playfulness.

It was a black-tie event that brought together hundreds of famous faces to recognize the 100 most influential people from around the globe. Time Magazine's 100 Most Influential People event was one of the biggest red carpet events of the year, and the chance for celebs to dress to the nines and show off their latest looks of the season.

Famous faces among the crowd included Barbara Walters, Elisabeth Hasselbeck, Stella McCartney, Clair Danes, Kate Hudson and Jimmy Fallon. What were some of the top fashion trends for this beautiful-people bash? Here's a rundown of the event's top looks:

Ruffles and Lace: Most celebrities were dressed in black from head to toe, but that doesn't mean there was anything boring or drab about their ensemble. Stars took their looks up a notch by sporting dresses trimmed with ruffles, lace and small bead accents. It was an elegant touch to an otherwise simple dress, and definitely a crowd-pleaser. These trim styles also add a feminine touch to suits, blazers and other masculine-inspired clothing.

Square-Neck Dresses: First Lady Michelle Obama was a guest at this event, and delivered a touching keynote speaking session as part of the festivities. She wore a beautiful floor-length gown designed with a square neck cut. It was the perfect fit for her figure, and one of the winning looks of the night.

Black and White Pinstripes: Pinstripes weren't reserved for the tuxedos and suits for this event. We caught signs of black and white stripes on skirts and blouses. It was a fresh, eye-catching look that was another winning ensemble for the night.

One-Shoulder Dresses: It's one of the season's hottest looks, and made its appearance several times on the red carpet at this celebrity event. The one-shoulder black dress trimmed with silver beads and lace is a show stopping look that won't be disappearing anytime soon. This type of dress doesn't require extra accessories either; many celebs just wore the dress without any accessories.

Draped Sleeves and Necklines: For celebs who wanted something simple and elegant, billowing sleeves and layered necklines helped create a chic and sophisticated look. The style is suitable for almost all figures, and showed up on dresses, blouses, and tunic tops.

The one shoulder dress has returned with celebrities.

Several celebrities have been seen wearing one shoulder dresses at events and parties. The one shoulder dress highlights the arms and the back and keeps the look sophisticated. Kate Moss is very into one shoulder dresses. Liv Tyler was seen wearing a one shoulder dress by Stella McCartney to the Incredible Hulk premiere. Other celebrities that glam it up in one shoulder dresses are Mandy Moore, Gwyneth Paltrow, Charlize Theron, Paris Hilton, Anne Hathaway and Becki Newton. The one shoulder dress is not the only article of clothing that is trendy with celebrities right now. Look out for one shoulder tops and blouses and also one shoulder bathing suits.

Yellow, yellow and more yellow. It seems like everywhere you turn you see someone wearing this bright summertime color. Yellow is huge among celebrities right now. Molly Sims wore a long yellow Versace dress on the red carpet, while Emmy Rossum sported a short yellow Phillip Lim dress to an event. The most dramatic yellow dress was worn by Rihanna. The dress was a long layered tiered dress by Giambattista Valli. She looked like she could have been Belle from "Beauty and the Beast." Shirts and shoes in yellow are also very trendy right now. If you are unsure about wearing a yellow dress, opt for a yellow shirt or add a splash of color to an outfit with yellow shoes. Just don't pair your yellow with too much black, as you may end up looking like a bumblebee.
