Beyoncé Knowles: The Showstopper

SHE NEVER MISSES WHEN IT COMES TO DRESSING LIKE A DREAMGIRL—ON AND OFF THE RED CARPET

ELEMENTS OF STYLE

• Mix Things Up
"Beyoncé absolutely loves fashion, and it's such a big part of her life," says mom and stylist Tina Knowles. "In her personal time she is eclectic, but I wouldn't call her trendy. She follows trends, but they don't define her style—she's very sophisticated and classic."

• Always Look Put Together
Whether she's dancing onstage or strolling in Saint-Tropez, she's always camera ready. "Even when she's in sweatpants she puts on a heel and a really nice necklace and cool earrings," says Mama Knowles. The consistency applies to handbags as well: "She's a purse fanatic—she's trying to buy every new handbag that comes out."

• Dress For Your Shape
B makes the most of her curvy figure, passing on last season's trendy loose babydolls in favor of fitted, waist-defining ensembles. And the vivid colors and sparkly metallics she chooses add to the eye-catching effect.

• Tailoring Is Key
Holmes's clothing may seem uncomplicated, but the fit is impeccable. The star's style displays "a sharp simplicity but is very chic," says designer Giambattista Valli, who hosted Holmes at his Paris show last fall. "She looks fabulous, but you see her first, then the clothes."

Drew Barrymore: The Chameleon

MODERN GLAMOUR ONE DAY AND RETRO CHIC THE NEXT, SHE'S MASTERED THE ART OF BEING ECLECTIC

ELEMENTS OF STYLE

• Follow Your Heart
You'll never see this Hollywood veteran get into a style rut: "Just keep taking risks and going for it, and don't play it safe . . . don't dress for what you think someone else will like," says Barrymore about her fashion philosophy. And it doesn't just apply to her clothes: Whether she rocks stick-straight hair and natural makeup or sultry eyes and an updo, Barrymore takes a look and works it head to toe. But somehow, it never comes across as high maintenance. "Her style is comfortably chic," says CoverGirl makeup artist Molly R. Stern, who's prettified the star.

• Break The Rules
Though her dresses are full-on glamorous, Barrymore always adds a bit of a rock-star edge with embellished necklines, dramatic makeup or chunky, eye-catching jewelry. Says Stern: "We have watched her grow into a sophisticated woman who still has traces of her funky youth."

COMBINING HIGH FASHION WITH STREET CHIC AND FUN ACCENTS (ANIMAL PRINTS, ANYONE?), SHE ALWAYS ROCKS

ELEMENTS OF STYLE

• Have No Fear
"There have been times that she's been on red carpet when she definitely pushes the envelope," says singer and pal Eve. "What makes Gwen an icon is she makes up her own rules." Which others are more than happy to follow: Her L.A.M.B. clothing and accessories line is one of the bestselling celeb brands.

• Embrace Patterns.
Stefani loves animal prints, plaids, camouflage and stripes—and isn't afraid to mix them in the same outfit. While the look isn't for the faint of heart, the star makes sure that the prints are balanced by proportioned silhouettes.

• Red Lipstick Goes With Everything
Whether she's in sweats or in a glamorous gown, Gwen rarely goes without her signature fire-engine-red lipstick. So how many tubes are in Stefani's makeup bag? "Way too many to count," she confesses.
