The first lady of fashion is really throwing down now—going head to head with one of Gossip Girl's resident fashionistas in this matching Marc Jacobs polka-dot dress.

Do you like your Pucci with a side of skin or silver panels? That's the face-off between foxy but age-appropriate Fonda and the sexy singer.
Jennifer Lopez & Salma Hayek
Gucci's blooming all over these A-list shoulders, from the Met Costume Institute Gala to the Cannes Film Festival, but whose bouquet do you like best?
Marisa Tomei, Beyoncé & Amy Smart
April showers brings May flowers, like these stars stepping out in three different versions of Preen's pretty floral frock. Who blooms best?

Jennifer Lopez & Kerry Washington
Gucci's color-block dress gets a love of love from Hollywood, but which plunging neckline do you prefer?
Kate Middleton & Rose McGowan
The brunette babes have figured out how best to flatter their figures in these sexy Issa halters—but who's your favorite?!
Olivia Palermo & Elle Fanning
Marchesa's frothy white mini gets very different treatments from these two stars with red satin stilettos versus Mary-Janes.
Jennifer Lawrence & Nicky Hilton
Hem length is the big difference between these matching Proenza Schouler sheaths with bustier tops. Long or short, where do you like your dress to fall?
Kate Bosworth & Taylor Swift
The frugal fashionistas duel over this little lace dress from London's Topshop, which cost a mere $98!
Tracy Morgan & Nick Cannon
Do these guys share the same stylist? Both wore a Moods of Norway jacket paired with a pop of pink recently to promote their respective projects, 30 Rock and America's Got Talent.
Kylie Minogue & Ciara
Kylie prefers to cover up in her fringed Pucci, while Ciara dares to bare it all. Which chanteuse rocks it best?
Jennifer Lopez & Fan Bing Bing
Peachy shades are the color du jour for the American Idol judge and the Asian superstar actress. La Lopez keeps her Elie Saab look simple, while Fan pairs hers with a bedazzled turban, matching cardigan and gold bling. Which star has this look wrapped up?
Jennifer Hudson, Kim Kardashian & Salma Hayek
Good things come in threes, we guess? All of these ladies are loving Alexander McQueen's epaulettes but who's head and shoulders above the rest?
(If Kim wears it best, sound off in comments since there are only two voting options!)
Sofia Coppola & Rihanna
One Céline sweater dress—styled for two different seasons. So are you a winter or spring fan?
Kate Beckinsale & Céline Dion
It's a sequins 'n' skin showdown as the actress and the singer square off in this glitzy Balmain gown with thigh-high slit.
Kate Beckinsale & Amanda Peet
It hardly seems like a fair fight—one's pretty in pink while the other opts to accessorize her lace Nina Ricci dress with quirky black tights—but let's put it to a vote!
Christina Aguilera & Selena Gomez
Do you like your Dolce & Gabbana with studs and spikes or pretty little bows?
Diane Kruger & Kate Bosworth
Same Dolce & Gabbana dress. Drastically different results as Diane goes sleek and pretty versus Kate's rough and tumble look.
Victoria Beckham & January Jones
The Mad Men star stepped out in this stunning 'n' structural Versace gown in January. But who can forget when Victoria Beckham attended Elton John's wedding six years ago in an almost identical dress by Roberto Cavalli?!
David Beckham & Adam Levine
The soccer stud and the Maroon 5 singer step out in almost identical outfits, each accessorizing his Ralph Lauren RRL sweater with slightly different elements.
Paris Hilton & Heidi Klum
They don't have much in common, but the party girl and the mom of four both seem to be fans of this gold Julien MacDonald gown—whether in Cannes back in 2005 and at this year's Grammy Awards, respectively.
Heidi Klum & Esperanza Spalding
It's the runway regular versus the fashion freshman as Heidi and Esperanza step out in the very same Suno jacket within weeks of each other.
