Marion Cotillard attended the premiere of ‘Public Enemies’ in London’s Leicester Square wearing a red satin Vivienne Westwood strapless bustier dress.

Her hair was elegantly styled into a beautiful quiff, whilst a black Stella McCartney Fall 2009 embossed faux leather clutch and black peep-toes completed the look.

90210’s actress Jessica Stroup was front row with Rihanna at Vivienne Westwood Spring 2010 show in Paris wearing the same dress.

Marion wins for me because I didn’t like how limp the bodice looked, or how overly creased Jessica’s dress was, nor the purple Brian Atwood Lola pumps she opted to wear with this dress.

Alexa Chung pulled this Luella Fall 2007 cute floral print mini dress out of her no doubt huge closet, to wear on the red carpet at the MTV Video Music Awards last month.

The cute mini dress has a poufy skirt aided by a black tulle underlay.

Alexa carried a black clutch and toughen up her cutesy look with manly boots.

Beatrice may have been inspired by Alexa, as she wore the same dress a few weeks later.

On a cold October night out with her sister Princess Eugenie, she didn’t wear a coat but opted for tights to keep her warm.

Beatrice has the perfect figure of this 50s style dress, it fits her better than Alexa, plus she ran an iron over it before she left her house unlike Alexa so Princess B wins for me.

Back in April, Rodeo Drive was the setting for supermodel Heidi Klum’s Vogue Germany photoshoot.

Crowds gathered to see her in a pose in a variety of looks ranging from Louis Vuitton to Alexander McQueen.

My favourite look was her Atelier Versace Spring 2009 strapless red paillette covered dress, worn with Gucci Fall 2009 heels and a red cardigan.

Emma Roberts disappointed many of you when she wore the same dress to the Costume Institute Gala the following month, as you’d hoped to see this dress on a bigger named celebrity who could carry such a complex stunning creation.

Cheryl Cole wowed us by wearing Atelier Versace for the second week in a row on the X Factor.

She was the only one to belt the dress, which she wore with Cesare Paciotti heels.

I don’t like any of the heels these ladies wore with dress, but I did love how Cheryl glowed in this dress and how the belt makes her waist so definded so she wins for me.

Keira Knightley and Kristen Dunst are huge fans of Rodarte, so the biggest surprise of this trio is Jennifer Lopez wearing this bronze bow accented Rodarte mini dress.

Keira wore the dress when she posed for the cover of Empire’s 20 Anniversary issue shot by Adrian Green, with fellow Brit actor James McAvoy.

Without a pout in sight, the actress wore her dress with black pointy heels.

All eyes were on Kristen Dunst when took her front row seat at the Rodarte Spring 2010 presentation last month.

She paired her dress with tight black tights despite the soaring heat during New York Fashion Week, plus black pumps.

Jennifer Lopez arrived at the “Fiesta Latina” event at the White House pairing her dress with matching strappy sandals and a box clutch.

Despite the fact that I was initially critical of Jennifer’s decision to wear this dress, her legs look amazing plus I much prefer her shoe choice so she wins for me.

This dress is available to purchase in a midnight blue print version from Collette for €2,635/£2,402.46/$3,917.98

LeAnn Rimes wore a silver layered Julia Clancey Spring 2008 dress when she walked the red carpet at the 2008 CMT Awards.

The country singer wore her dress with layered necklaces and marcel waves to complete her 1920s flapper style look.

Shanna Moakler wore the same dress when she arrived at the “Smoak” cosmetic launch in LA last week.

Both women wore silver heels, but I must prefer Shanna’s sparklers.

This silver dress really didn’t need any added jewelry, so Shanna wins for me.

Katie Cassidy wearing this shimmering Brian Lichtenberg Fall 2009 one-sleeved navy dress with a padded shoulder to the “Melrose Place” Premiere Party in LA this summer, was the moment she put herself on my radar and I have been in love with everything she has worn ever since.

She teamed her dress with Bebe Desiree leather caged sandals and a Swarovski clutch to completed her stunning look.

Paris Hilton is known for wearing mini dresses. It’s very much her trademark red carpet look, as she has amazing legs and loves to show them off.

This week at the “2009 Fox Reality Channel Really Awards” she wore the same Brian Lichtenberg dress with Versace heels, but sadly without the same wow factor.

Katie wins for me.

Ciara attended the Los Angeles Premiere of “Orphan” in July wearing a Gryphon sequin racerback tank paired with leather pants and black pumps.

This was back in the day when she was sporting a shorter cropped ‘do.

Serena Williams wore the same sparkling tank to the “Whip It” premiere last month, opting to wear hers with a black blazer, cropped pants, black heels and gold accessories.

I love way both ladies wore this look. Ciara’s look was edgy, whereas Serena look was very smart.

I’m not a big fan of leather pants, especially when worn in summer so I will give the win to Serena.
