Mel B and Joanna Krupa wore the same skimpy lace and mesh dress to Oscars after parties in Los Angeles on March 2, 2014. The former Spice Girl wore hers to the Elton John AIDS Foundation's Oscar Viewing Party, while Joanna donned a similar look to the Fame & Philanthropy Post-Oscar Party. There's sexy, and then there's a little too sexy. We're giving this round to Krupa.

Kim Kardashian donned a gray Donna Karan wrap dress outside her family's Dash boutique in Los Angeles on Oct. 10, 2013. The next day, Jennifer Hudson sported the same frock to the premiere of "The Inevitable Defeat of Mister and Pete" in Chicago on Oct. 11. And on Nov. 19, 2013, LeAnn Rimes showed up at a Los Angeles gala in the same dress! Each star wore the clingy creation in a different way. LeAnn wrapped the dress low, Jennifer wrapped the dress high, and Kim rocked a deep cowl. We'll give this point to Jennifer, though: Her sleeker take accentuates her curves and doesn't look droopy or overly revealing.

It's Celine vs. Selena in the style department! She might be twice her age, but Celine Dion didn't have any qualms about challenging 21-year-old Selena Gomez to a fashion faceoff when she wore the exact same dress as the young star at "The Voice" finale. The 45-year-old has a career spanning over 20 years and it appears she's not ready to throw the towel in yet, taking to the center stage with Ne-Yo in a sexy zip dress that certainly got tongues wagging. Gomez was first spotted wearing the Versace gown at the MTV Video Awards earlier this year.

England representin': Brits Harry Styles and Victoria Beckham just LOVE the iconic English label Burberry. While Posh generally has her finger on the pulse when keeping up with the latest trends, it seems the fashion mogul may have some competition in the Styles department! Harry Styles was seen wearing this heart-print Burberry shirt first to the One Direction "This Is Us" movie premiere on Aug. 20, while Posh pulled off the impossible (again), looking effortlessly chic after a long flight on Sept. 2.

Always one to keep up with the latest trends, Katy Perry was true to form wearing a graphic printed crop top and high-waisted skirt at Nickelodeon's 26th Annual Kids' Choice Awards on March 23. Spotted wearing the exact same outfit, Cara Santana gave Katy a run for her money at the 13th Annual InStyle Summer Soiree.

Lily Aldridge liked Kim Kardashian's outfit so much, she decided to copy it piece by piece! The Victoria's Secret model was spotted out in New York City wearing the exact same Givenchy maxi dress the pregnant reality star rocked on Feb. 27, 2013. Both ladies kept things edgy by accessorizing with black leather jackets and peep-toe heels.

Selena Gomez's single-breasted look at the MTV Video Music Awards seemed shocking, until Lady Gaga stepped out wearing it -- and pretty much only it. The skin-tight bra/corset designs are Atelier Versace. Gomez wore hers to an awards show. Gaga decided the bra-top look was appropriate for the airport.

When it comes time to hit the campaign trail, there's no better person to take style cues from than Michelle Obama. Huma Abedin, wife of New York City mayoral candidate Anthony Weiner, took a page from the First Lady's book as she appeared by her husband's side in Harlem wearing a bright and breezy red and white checkered dress on July 14, 2013. It was the same look Mrs. O donned during a campaign stop in Dubuque, Iowa on Aug. 15, 2012.

When the stars want to stand out, they turn to Tom Ford. The designer's metallic blue column dress has made its way to the red carpet not once, but THREE times, which of course begs the question -- who wore it best? Jennifer Lopez was the latest to squeeze her curves into the shimmery sapphire creation at the amfAR Inspiration Gala in New York City on June 13, 2013. Liberty Ross wore the gown to the London premiere of "Snow White and the Huntsman" in May 2012, while fellow model Lily Cole donned the popular dress at the 2011 Harper's Bazaar Women of the Year Awards. Although all three ladies looked stunning, we're giving this round to J.Lo, who appeared the most confident striking a pose in the dazzling getup.

Three stunning ladies, one stunning dress. Jennifer Lawrence, Kim Kardashian and Jennifer Lopez were all spotted wearing this sexy zipper dress by Tom Ford, but we gotta say that with her enviable curves on full display, Kim takes this round hands down.

Everyone's a winner when you have two supermodels battling it out in the same dress. Petra Nemcova and Cindy Crawford both looked white hot in Roberto Cavalli as they hit up the Cannes Film Festival in the South of France wearing the same halter gown just days apart from each other.

Zoe Saldana put her thin pins on display in bold Balmain at the Berlin premiere of her movie "Star Trek Into Darkness" on April 29, 2013. A month later, Liberty Ross rocked the same frock in toned down blue and black at the amfAR Cinema Against AIDS gala in Cannes on May 23, 2013. Both outfits look great, but we appreciate any woman daring enough to wear fuchsia on the red carpet. Point goes to Zoe!

It's the battle of the cleavage! "2 Broke Girls" star Kat Dennings poured her va-va-voom curves into a body-hugging navy blue dress by Vivienne Westwood as she hit the red carpet for a Television Critics Association party on July 29, 2012. It's a jaw-dropping look we've seen another buxom beauty pull off in the past. "Mad Men" star Christina Hendricks squeezed her famous hourglass figure into a similar version of the dress with a slightly longer hemline last September. As for who wore it best? We'll call this one a tie.

Gender-bending model Andrej Pejic modelled this sheer disaster on the runway before Rihanna took it to the Grammy's. Point goes to Pejic, seeing as he's a man and he looks just as good in the dress. Now that's called being good at your job!

Wearing sweats out in public is always something of a fashion no-no, but both Kanye West AND Rihanna were willing to put comfort before style when they picked out these shapeless black pants. It's hard to declare a faceoff winner here. While RiRi added a touch of class to her outfit, pairing her pajama-like bottoms with a teetering pair of white heels and a backwards baseball hat during an L.A. Clippers game on April 7, 2013, West kept things edgy by throwing on one of his numberless black leather jackets to attend a Versace store opening in New York City in 2012. We call this sloppy-chic look a draw.

Stella McCartney is always a favorite with the stars, but this whimsical-looking dress with its peek-a-boo cut-outs is especially a hit! LeAnn Rimes, Brooklyn Decker, Nicole Kidman and Gwyneth Paltrow all rocked different variations of the frock on the red carpet. But while each lady looks lovely, we're giving this round to Brooklyn for keeping things simple with her hair, makeup and shoes.
