Here we have a WWIB poll with three celebs wearing the same dress in different colours.

First up, Rooney Mara who, on a rare occasion, broke out of her all-black sombre looks to shine on the red carpet wearing a Louis Vuitton Pre-Fall 2012 green sleeveless dress to the 27th Annual Santa Barbara Film Festival Virtuosos Awards.

She wore her cute dress with Giambattista Valli heels, keeping the rest of the look clean and fresh by simply pulling her short hair back into a low ponytail.

Dianna Agron wore the black version of the dress when she attended the Louis Vuitton Fall 2012 presentation during Paris Fashion Week.

She kept the look interesting by adding a green choker. The rest of her accessories included a sparkly black clutch, black tights and sparkled-cap Louis Vuitton heels.

Reese Witherspoon was the only one to belt her Louis Vuitton dress when she took to the red carpet in Brazil for the premiere of her latest movie, ‘This Means War’.

The blonde beauty also added a statement necklace and completed her look with Jimmy Choo ‘Greta’ sandals.

You’ll be surprised to know that Dianna wins for me.

I loved the colours of both Rooney and Reese, but I didn’t like Rooney’s makeup and I didn’t like how Reese styled her dress.

Dianna’s chic accessories won me over.
