Kim Kardashian and Erin Andrews may have missed competition on Dancing with the Stars by a few seasons, but the girls go face-to-face in today’s Who Wore It Best.  The sexy sportscaster and the reality show personality stepped out in exactly the same Wayne mini months apart, and though they both looked great in it, only one of them looked the Best!

Kim Kardashian wore the sheer-overlay one-shouldered mini to the launch of The Kim Kardashian Vanilla Cupcake Mix at Famous Cupcakes in Beverly Hills in February.  Paired with Christian Louboutin patent leather pumps, a blinging ring and earrings, Kim wore her long hair in bouncing curls.

Even celebs love a bargain, but what happens when they pinch pennies on the exact same frock? We spotted Eva Longoria Parker over the weekend wearing a two-toned jumper, which looked a tad familiar. That's because Rachel Bilson rocked the Ruffled-Front Halter Jumper to an event back in April.

Rachel hit the red carpet of the Express Rerock Denim event at Tao Beach in Las Vegas wearing the flirty romper (with her lacy bra peeping out the top) belted in black over matte black tights. Sporting buckled Miu Miu booties on her feet, the OC star looked totally edgy.

It was a battle of the white hot babes, when RadarOnline.com spotted two Hollywood style sirens in the exact same Camilla and Marc dress.  It is not hard to see why the entertainment correspondent and the Entourage ingénue fell for the Grecian-style, one-shouldered mini, which featured leather panels and a gold embellished neckline, but unfortunately only one of them will go home as our wardrobe winner!

Shaun Robinson was in charitably chic form at the 12th Annual HollyRod DesignCare Event, which was held at Ron Burkle’s Green Acres Estate in Beverly Hills over the weekend. The style star paired the gorgeous form-fitting frock with metallic peep-toed heels, a gold clutch and dangling earrings for a sophisticated yet sassy look.

What the Access Hollywood beauty probably didn’t know, was that Dania Ramirez rocked the exact same “Alexander” frock to the Maxim Hot 100 Party all the way back in May. The breakout bombshell paired the sexy mini with silver embellished Jimmy Choo heels and a colorful cuff bracelet, for a truly sexy look.

It is a war of the divas when two of the biggest Hollywood bombshells step out in exactly the same frock! Rihanna hit the town on Monday night in Los Angeles looking tres glam in the identical drapy, matte black, one-shouldered Lanvin Spring 2010 frock that Jennifer Lopez wore to the London premiere of The Back-Up Plan a few months ago.

When Jennifer Lopez strut her stuff down the red carpet of her UK movie premiere in April, all heads were turning. Only the most delightful of divas could pair a high-tech constructed asymmetrical dress with a statement turquoise necklace, a fancy beehive and a thick black belt and actually get away with it!

Paris Hilton and Shaun Robinson both have an affinity for one-sleeved dresses, which isn’t a surprise, because nearly everyone in tinseltown owns one. The thing is, the heiress and the Access Hollywood correspondent have worn the exact same Preen Maximum dress from ARCADE Boutique in different colors to different events over the past few months.

Paris got to the designer dress first, wearing it to the Chagoury Couture Fashion Show in April. Pairing the carnation pink number with nude Christian Louboutin heels and a whole lotta bling, the heiress looked super sexy without showing too much skin.

What happens when a pretty Pussycat Doll rocks the exact same frock as a divine Diva, who rocks the exact same frock as a gorgeous Gossip Girl? A fierce fashion face off, and only one glamazon will go home with the haute honors! Nicole Scherzinger was dressed to judge at the X Factor in the UK last week, wearing the exact same Victoria Beckham Spring 2010 mini that Jennifer Hudson wore in January, that Blake Lively wore back in October 2009. Now that is what we call one popular peplum dress!

Blake was the first fashionista to rock the Posh frock, dropping jaws when she walked the red carpet of the 2009 Angel Ball in NYC in the super refined mini, which she paired with steel-toed Christian Louboutin Calypso heels.
