Who Wore it Best?

Rihanna was spotted in Los Angeles International Airport (with her entourage in tow) on January 3, 2009 wearing a pair of Charley 5.0 Skinny Tie Dye Legging Jeans with an oversized mesh sweater, hot pink Givenchy sandals and blue and brown sunglasses. But Ciara rocked the same leggings with a loose tank and black platform heels last June on the red carpet at the Hollywood premiere of "Transformers."

Jennifer Lopez wore an A.L.C. navy & white striped maxi dress at the Dolphins vs New England Patriots football game in Miami on December 6, 2009. We remember Rihanna wearing the same dress dress in August. The two singers both paired their long, flowy dresses with big-framed sunglasses.

Georgina Chapman wore a lovely strapless satin dress (from her own line, Marchesa) to an event on July 25, 2009 in Los Angeles. Susan Lucci liked the look enough to copy it for a gala in New York on October 26, 2009.

Aussie model Lara Bingle wore Louis Vuitton to an event for the brand on October 29, 2009 in Melbourne, Australia. Months earlier, Rihanna wore the same one to a gala at Cipriani in New York City. Predictably, the pop star paired it with lace-up black combat boots for an edgier look.

Serena Williams looked chic in this modern take on the pant suit at the "Whip It" premiere on September 29, 2009 in Los Angeles, California. The tennis pro wore a Gryphon sequin racerback tank, cropped pants, and peep-toe heels. But we remember spotting Ciara at the Los Angeles premiere of "Orphan" on July 21, 2009 in the same gold top with leather leggings and black pumps. The singer's razor sharp cut screams bad girl!

Ashlee Simpson-Wentz attended The CW Fall Preview party in Beverly Hills, CA on September 14, 2009 wearing a black and white Nuj Novakhett minidress. The redhead starlet broke the fashion rules when she paired it with pointy white pumps. But Kim Kardashian first rocked the striped frock back in June to the Much Music Video Awards in Toronto, Canada. The reality TV star accessorized with a black leather belt, pumps, and a mini clutch.

"Whip It" director and star Drew Barrymore wore this lace sleeved Stella McCartney dress and Alai booties while promoting her new film in Los Angeles, CA on September 28, 2009 in Los Angeles, California.

90210 starlet Jessica Stroup attended the Vivienne Westwood show during Paris Fashion Week on October 2, 2009 wearing this red strapless number by the designer. And she added contrast with Brian Atwood "Lola" suede purple pumps. Marion Cotillard served up Parisian chic when she donned the same satin frock to the London premiere of "Public Enemies" on June 29, 2009. Marion's sleek pompadour and black accessories create a rocker-esque appeal.
