Victoria Beckham
Ritzy and Risky ≫

▪ Her Look
The epitome of flamboyant Brit-chic, she's famous for working towering platforms, oversize sunglasses and vacuum-packed-tight outfits. "The skinny jean will always be a favorite of mine," Beckham, 33, told PEOPLE earlier this year.

▪ Fashion Cred
She launched the dVb denim line—featuring hotpants with a 2-in. inseam!—in August and penned a style guide that generated a surprising amount of buzz abroad. When the new L.A. resident wore Giambattista Valli platforms to her "Welcome to America" party, the designer says, "we sold out immediately."

Inspired By Her Look

Trading in her dark brown locks for a razored bob, Beckham created the hairstyle of the year, with friends like Katie Holmes and other stars following suit. "She's very influential," says Valli. "She is always very radical, but she knows exactly what she likes."

POSH'S TIPS

From her book

That Extra Half an Inch: Hair, Heels and Everything In Between, which debuts stateside Nov. 13:

1. Invest in practical clothing.

2. Plan your outfit the night before.

3. Bring your husband when shopping for lingerie.

4. Have a chic pregnancy.

Why Doesn't Victoria Smile?

▪ She's Sad?
No. People "have this impression that I'm this miserable cow," Beckham told W. "But I'm actually quite the opposite."

▪ She's Angry?
Try disoriented. Posh blames the paparazzi: "When you're out there...with all the flashes, it's as much as you can do to just find your car," she said.

▪ She Has Bad Teeth?
Don't be naff. Her plan to dismiss the rumor? "I'm going to try and smile more for America."

RISQUE BUSINESS

Posh's boldest look this year? The Chanel shorts and Cavalli top she paired with a cropped vintage Gaultier jacket to attend an awards show in London.

Kate Moss
Edgy and Eclectic

▪ Her Look
You name it. Moss, 33, can make casual vests, fringed boots and animal prints look runway-worthy.

▪ The Trendsetter
Moss always manages to showcase the next hot thing. Case in point: After single-handedly starting last fall's skinny-jean craze, she ran around in high-waisted, wide-legged jeans, sparking this fall's new trend.

▪ Fashion Cred
Her first clothing line for Topshop—inspired by pieces in Moss's own closet—launched in May with wannabes rushing the racks for a rationed five items.

▪ Her Look
Prom princess with a sporty-punk edge. The hip-hop sweetheart is famous for pairing white sneakers with frilly colorful dresses. "I like to try out different looks, like smart with scruffy," Allen, 22, recently told Harper's Bazaar.

▪ Fall Fashion
Tip "Go for bright accessories," she's said.

▪ Fashion Cred
Allen's look inspired a line of dresses called Lily Loves, which launched in Britain this May. The clothes, available in U.S.-equivalent sizes 4 to 14, defy the stick-thin celebrity trend. "You know how I feel about fashion: It's for everyone, not just a load of superskinny models," Allen said.

Kate Middleton
Perfectly Proper

▪ Her Look
Tailored blazers, knee-length skirts and elegant dresses give the poised royal-in-waiting an understated sophistication.

▪ Fashion Cred
Middleton, 25, got her start in the fashion biz by working as an assistant accessories buyer for trendy Brit chain Jigsaw. And after she wore a simple $80 black-and-white dress from Topshop to work, it sold out overnight.

▪ Fit for a Princess
With a fashion sense often compared with the late Princess Diana's, "Prince William's possible future bride seems to have learned from the woman who might have been her mother-in-law," said veteran fashion writer Suzy Menkes, who also tracked Diana's famously evolving style.

Emma Watson
Polished and Perky

▪ Her Look
Trading Hogwarts' robes for chic dresses, the 17-year-old blossomed into a fashion whiz this year. Watson paired outfits with girly flats and stepped up the elegance in Chanel for several Harry Potter and the Order of the Phoenix premieres, sweetly balancing high fashion and age-appropriateness.

▪ Her Fashion Cred
According to Vogue.com, she recently signed on with Storm modeling agency—the same company that "discovered" supermodel Kate Moss years ago—and has already graced the covers of magazines.

▪ Her Style Philosophy
"I want the clothes to be an expression of me," Watson told Britain's Tatler magazine.
