Modern Fashion Icon - Chloë Sevigny

Chloë Sevigny

• In her closet: Her Opening Ceremony line, Valentino, Proenza Schouler, Chloé
• Iconic look: One-shoulder, polka-dot Isaac Mizrahi gown at the Emmys, 2009
• Key accessory: Bare legs
• Thing you can't imitate: Actual acting ability

She's appeared on not just her pal Tara Subkoff's Imitation of Christ runways, but also on the catwalk at Dolce & Gabbana; labels from Chloé to Uniqlo have used her in their ad campaigns; she's a favorite of designers like Stefano Pilati and the Proenza Schouler boys; and she has her very own collection for Opening Ceremony. But the ultimate proof of Sevigny's icon status? Even the austere sister-wife style of her Big Love character has been influential. How else to explain the side braid at Alexander Wang and Miu Miu's Spring shows?

Modern Fashion Icon - Kate Moss

Kate Moss

• In her closet: Vintage
• Iconic look: Dashing to the store in skinny jeans, a tank, and a shrunken jacket, and looking like 9 million bucks (her annual income, according toForbes)
• Key accessory: Indie rocker boyfriend
• Thing you can't imitate: The attitude

Wellies, denim cutoffs, men's blazers, skinny jeans, ballet flats, skull scarves, fringy boots, fur chubbies, motorcycle boots, shrunken vests…basically, everything you've had or wanted to have in your closet over the past ten years first appeared on the back, foot, neck, or arm of the unsinkable supermodel. And if you want a piece of the Brit's look, you'd better hurry to Topshop, where Moss' signature line—an unapologetic rehashing of her greatest hits—will have its last full collection this fall.

Modern Fashion Icon - Sarah Jessica Parker

Sarah Jessica Parker

• In her closet: Oscar de la Renta, Halston Heritage, Chanel, Alexander McQueen
• Iconic look: Philip Treacy butterfly spectator hat and acid green Alexander McQueen dress at the Sex and the City 2 premiere in London, 2010
• Key accessory: "Manolos!"
• Thing you can't imitate: The ability to give a designer a major fashion credit in your movie

Two words: Carrie Bradshaw. With stylist Patricia Field hovering off-screen, SJP's alter ego made Mr. Blahnik a household name and popularized off-beat accessories from flower pins to nameplate necklaces—not to mention legitimizing spending as a form of empowerment, therapy, and, above all, fun. Whatever you think of the aftereffects—and it is now officially impossible to traverse certain areas of New York City without stumbling into hordes of the over-accessorized—Parker's affection for fashion seems beguilingly sincere, as her decision to lay it on the line as creative director at Halston Heritage shows.

Modern Fashion Icon - The Olsen Twins

The Olsens

• In their closets: The Row, Givenchy, Rick Owens, Balenciaga, Giambattista Valli
• Iconic look: "Dumpster chic"
• Key accessory: Then: venti Starbucks cup. Now: soon-to-debut bag from The Row
• Things you can't imitate: Hair, bank balance

Both lauded and lambasted mid-decade for draping their waifish frames with oversize layers to stalk through the NYU campus, Mary-Kate and Ashley graduated to become major trend igniters (not to mention the respected designers of their own lines, The Row and Elizabeth and James). Last spring, we wondered if the "anti-fashion" the twins had suddenly taken to wearing was a harbinger of things to come. One look at the pared-down Fall collections—from Dries to Celine—and, well, we think we have our answer.

Modern Fashion Icon - Michelle Obama

Michelle Obama

• In her closet: Jason Wu, Narciso Rodriguez, Zero + Maria Cornejo, J.Crew, Rodarte, Talbots, Azzedine Alaïa
• Iconic outift: Chartreuse-yellow Isabel Toledo dress and coat on Inauguration Day, 2009
• Key accessory: Lanvin sneakers
• Thing you can't imitate: The photo ops

Let's get the cheesy clichés out of the way at the beginning: Michelle Obama, our commander-in-chic, has proudly exercised her right to bare arms. There now! Touted as the savior of Seventh Avenue before her husband was even sworn in, the First Lady has in fact crafted a look that's totally non-hyperbolic: She's an everywoman with smart high-low taste, a good figure, and, on occasion, the need to dress for a black-tie event with the world's most powerful rulers in attendance. Her efforts have landed her on Vanity Fair's International Best-Dressed List for four years running, an unheard-of achievement for someone who isn't married to a minor European nobleman.
